Mariah Carey (born March 27, 1969^[2] or 1970)^[3] is an American singer, songwriter, actress, record producer, and entrepreneur. Referred to as the "Songbird Supreme" by the Guinness World Records, she is noted for her five-octave vocal range, melismatic singing style, and signature use of the whistle register. She rose to fame in the early 1990s after signing to Columbia Records and releasing her eponymous debut album, which topped the U.S. Billboard 200 for eleven consecutive weeks. Soon after, Carey became the only artist ever to have their first five singles reach number one on the U.S. Billboard Hot 100 chart, from "Vision of Love" to "Emotions".^[4]

Following her marriage to Sony Music head Tommy Mottola, Carey achieved worldwide success with follow-up albums Music Box (1993), Merry Christmas (1994), and Daydream (1995). These albums spawned some of Carey's most successful singles, including "Hero", "Without You", "All I Want for Christmas Is You", "Fantasy", "Always Be My Baby", as well as "One Sweet Day", which became the longest-running U.S. number-one single in history (sixteen weeks) from 1996 until 2019. After separating from Mottola, Carey adopted a new image and incorporated more elements of hip hop into her music with the release of Butterfly (1997). Billboard named her the country's most successful artist of the 1990s, while the World Music Awards honored her as the world's best-selling recording artist of the 1990s.

After eleven consecutive years charting a U.S. number-one single, Carey parted ways with Columbia in 2000 and signed a $100 million recording contract with Virgin Records. However, following her highly publicized physical and emotional breakdown, as well as the critical and commercial failure of her film Glitter (2001) and its accompanying soundtrack, her contract was bought out for $50 million by Virgin and she signed with Island Records the next year. After a relatively unsuccessful period, she returned to the top of music charts with The Emancipation of Mimi (2005), which became the world's second best-selling album of 2005. Its single, "We Belong Together", made her the only artist to top the Billboard Hot 100 Decade-End chart twice. With the release of "Touch My Body" (2008), Carey gained her eighteenth number-one single in the United States, more than any other solo artist. The next year, she starred in the critically acclaimed film Precious, which won her Breakthrough Actress Performance Award at the Palm Springs International Film Festival.

Throughout her career, Carey has sold more than 200 million records worldwide, making her one of the best-selling music artists of all time. According to the Recording Industry Association of America (RIAA), she is the third-best-selling female artist in the United States, with 64 million certified albums.^[5] In addition to this, she is listed as the female songwriter and producer with the most number one songs in U.S. chart history. In 2012, she was ranked second on VH1's list of the 100 Greatest Women in Music. Aside from her commercial accomplishments, Carey has won five Grammy Awards, nineteen World Music Awards, ten American Music Awards,^[6] and fifteen Billboard Music Awards.^[7] She has consistently been credited with inspiring a generation of singers, and is hailed as being one of the pioneers of pop and contemporary R&B music.^[8]

Mariah Carey was born in Huntington, New York.^[9][10] Her father, Alfred Roy Carey, was of African American and Afro-Venezuelan descent, while her mother, Patricia (née Hickey), is of Irish American descent. According to Mariah, her maternal grandparents were "from Ireland".^[11] The last name Carey was adopted by her Venezuelan grandfather, Francisco Núñez, after he came to New York.^[12] Patricia was an occasional opera singer and vocal coach before she met Alfred in 1960.^[10] As he began earning a living as an aeronautical engineer, the couple wed later that year, and moved into a small suburb in New York.^[12] After their elopement, Patricia's family disowned her for marrying a black man. Carey later explained that growing up, she felt neglected by her maternal family, which greatly affected her.^[12] During the years between the births of Carey's older sister Alison and herself, the Carey family struggled within the community due to their ethnicity.^[12] Carey's name was derived from the song "They Call the Wind Maria", originally from the 1951 Broadway musical Paint Your Wagon.^[13][14] When Carey was three, her parents divorced.^[15]

After their separation, Alison moved in with her father, while the other two children, Mariah and brother Morgan, remained with their mother. Carey would grow apart from her father, and would later stop seeing him altogether.^[15][17] By the age of four, Carey recalled that she had begun to sneak the radio under her covers at night, and just sing and try to find peace within the music.^[17] During elementary school, she excelled in subjects that she enjoyed, such as music, art, and literature, but did not find interest in others. After several years of financial struggles, Patricia earned enough money to move her family into a stable and more affluent area of New York.^[18] Carey had begun writing poems and adding melodies to them, thus starting as a singer-songwriter while attending Harborfields High School in Greenlawn, New York,^[19] where she graduated in 1987.^[20] Carey excelled in her music, and demonstrated usage of the whistle register, though only beginning to master and control it through her training with her mother. Though introducing her daughter to classical opera, Patricia never pressured her to pursue a career in it, as she never seemed interested. Carey recalled that she kept her singer-songwriter works a secret and noted that Patricia had "never been a pushy mom. She never said, 'Give it more of an operatic feel.' I respect opera like crazy, but it didn't influence me."^[19][21]

While in high school, Carey began writing songs with Gavin Christopher. They needed an assistant who could play the keyboard: "We called someone and he couldn't come, so by accident we stumbled upon Ben [Margulies]. Ben came to the studio, and he really couldn't play the keyboards very well – he was really more of a drummer – but after that day, we kept in touch, and we sort of clicked as writers."^[21] Carey and Christopher began writing and composing songs in the basement of his father's store during Carey's senior year. After composing their first song together, "Here We Go 'Round Again", which Carey described as having a Motown vibe, they continued writing material for a full-length demo.^[22] She began living in a one-bedroom apartment in Manhattan, which she shared with four other female students.^[23][24] Carey worked as a waitress for various restaurants, usually getting fired after two weeks.^[25] While requiring work to pay for her rent, Carey still had musical ambitions, as she continued working late into the night with Margulies in hopes of completing a demo.^[25] After completing her four song demo tape, Carey attempted to pass it to music labels, but failed each time.^[26] Shortly thereafter, she was introduced to rising pop singer Brenda K. Starr.^[26][27]

As Starr's friendship with Carey grew, so did her interest in helping Carey succeed in the industry. In December 1988, Carey accompanied Starr to a record executives' gala, where she handed her demo tape to the head of Columbia Records, Tommy Mottola, who listened to it on his way back home.^[28][29] After the first two songs, he was interested in her; later, after searching for Carey for two weeks, he immediately signed her and began mapping out her commercial debut.^[28] While she maintained that she wanted to continue working with Margulies, Mottola enlisted top producers of the time, including Ric Wake, Narada Michael Walden and Rhett Lawrence.^[28] Mottola and the staff at Columbia had planned to market Carey as their main female pop artist, competing with Whitney Houston and Madonna (signed to Arista and Sire Records respectively).^[30] After the completion of her debut album, Mariah Carey, Columbia spent more than $1 million promoting it.^[31] Despite a weak start, the album eventually reached the top of the Billboard 200, after Carey's exposure at the 33rd Annual Grammy Awards.^[32] Mariah Carey stayed atop the charts for eleven consecutive weeks,^[33] and she won the Best New Artist, and Best Female Pop Vocal Performance awards for her single "Vision of Love."^[34] In addition to "Vision of Love", the album yielded the Billboard Hot 100 number one singles "Love Takes Time", "Someday", and "I Don't Wanna Cry".^[35] Carey became the first musical act since the Jackson 5 to have their first four singles reach number one.^[36] Mariah Carey finished as the best-selling album in the United States in 1991,^[37] while totaling sales of over 15 million copies.^[38]

Carey began recording her second studio album, Emotions, in 1991.^[39][40] She described it as an homage to Motown soul music, as she felt the need to pay tribute to the type of music that had influenced her as a child.^[40] For the project, Carey worked with Walter Afanasieff, who only had a small role on her debut, as well as Robert Clivillés and David Cole, from the dance group C+C Music Factory.^[41] Carey's relationship with Margulies deteriorated over a personal contract Carey had signed with him before signing the record deal with Columbia, agreeing to split not only the songwriting royalties from the songs, but half of her earnings as well. However, when the time came to write music for Emotions, Sony officials made it clear he would only be paid the fair amount given to co-writers on an album. Margulies later filed a lawsuit against Sony which ultimately led to their parting of ways.^[40] Emotions was released on September 17, 1991, and was accepted by critics as a more mature album than its predecessor.^[42] While praised for Carey's improved songwriting, production, and new sound, the album was criticized for its material, thought weaker than that of her debut.^[43] Though the album managed sales of over eight million copies globally, Emotions failed to reach the commercial and critical heights of its predecessor.^[44]

As after the release of her debut, critics again questioned whether Carey would embark on a world tour to promote her material.^[45] Although Carey explained that stage fright and the style of her songs made a tour very daunting, speculation grew that Carey was a "studio worm," and that she was incapable of producing the perfect pitch and 5-octave vocal range for which she was known.^[46][47] In hopes of putting to rest any claims of her being a manufactured artist, Carey and Walter Afanasieff decided to book an appearance on MTV Unplugged, a television program aired by MTV.^[48] The show presented name artists "unplugged" or stripped of studio equipment.^[48] While Carey favored her more soulful and powerful songs, it was decided that her most popular content would be included. Days before the show's taping, Carey and Afanasieff thought of adding a cover version of an older song, in order to provide something different and unexpected.^[49] They chose "I'll Be There", a song made popular by The Jackson 5 in 1970. On March 16, 1992, Carey recorded a seven-piece set-list at Kaufman Astoria Studios in Queens, New York.^[50] The revue was met with critical acclaim, leading to it being aired more than three times as often as an average episode would.^[51] The success tempted Sony officials to market it.^[52] Sony decided to release it as an EP, priced low because it was short. The EP proved to be a success, contrary to critics and speculations that Carey was just a studio artist,^[53] and was given a triple-Platinum certification by the Recording Industry Association of America (RIAA),^[54] and managed Gold and Platinum certifications in several European markets.^[52]

During early 1993, Carey began working on her third studio album, Music Box.^[55] After Emotions failed to achieve the commercial heights of her debut album, Carey and Columbia came to the agreement that the next album would contain a more pop-influenced sound in order to appeal to a wider audience.^[55] During Carey's writing sessions, she began working mostly with Afanasieff, with whom she co-wrote and produced most of Music Box.^[56] On August 31, Music Box was released around the world, debuting at number-one on the Billboard 200.^[57] The album was met with mixed reception from music critics; while many praised the album's pop influence and strong content, others felt that Carey made less usage of her acclaimed vocal range.^[58] Ron Wynn from AllMusic described Carey's different form of singing on the album: "It was wise for Carey to display other elements of her approach, but sometimes excessive spirit is preferable to an absence of passion."^[59]

After declining to tour for her past two albums, Carey agreed to embark on a short string of concerts in late 1993, titled the Music Box Tour.^[60] Spanning only six dates across the United States,^[60] the short but successful tour was a large step for Carey, who dreaded the hassle of touring.^[61] With the release of the album's second and third singles, Carey achieved several career milestones and expanded her popularity throughout Europe. "Hero" became Carey's eighth chart topper in the United States^[62] and would eventually come to be one of the most popular and inspirational songs of her career,^[62] while her cover of Badfinger's "Without You" became her first number one single in Germany,^[63] Sweden,^[64] and the United Kingdom.^[65] Music Box spent prolonged periods at number one on international album charts^[66] and eventually became one of the best-selling albums of all time, with worldwide sales of over 28 million copies.^[67]

Following Music Box, Carey recorded a duet with Luther Vandross; a cover of Lionel Richie and Diana Ross's "Endless Love", and began working on an unknown project throughout the summer of 1994.^[68] In October, Billboard announced that she would release a holiday album later that year.^[68] Carey's album Merry Christmas was released on November 1, 1994^[69] and eventually became one of the best-selling Christmas albums of all time, with global sales of over 15 million copies.^[70][71][72] Upon its release, the album's first single, "All I Want for Christmas Is You", was described as a "holiday standard"^[73] and considered "one of the few worthy modern additions to the holiday canon."^[70] Commercially, it became the world's 10th best-selling single by December 2018, with global sales exceeding 16 million copies.^[74] By the end of the holiday season of 1994, Carey and Afanasieff had already begun writing material for her next studio album which would be released late the following year.^[75]

Released on October 3, 1995, Daydream combined the pop sensibilities of Music Box with downbeat R&B and hip hop influences.^[76] Critically, the album was heralded as Carey's best to date; The New York Times named it one of 1995's best albums, and wrote, "best cuts bring R&B candy-making to a new peak of textural refinement [...] Carey's songwriting has taken a leap forward and become more relaxed, sexier and less reliant on thudding clichés."^[77] The album's second single, "One Sweet Day", a collaboration with R&B group Boyz II Men, remained atop the Billboard Hot 100 for a record-breaking 16 consecutive weeks, becoming the longest-running number-one song in history.^[78] Daydream became her biggest-selling album in the United States,^[79] and became her second album to be certified Diamond by the RIAA, following Music Box.^[54] The album sold 2.2 million copies in Japan alone and eventually reached global sales of over 25 million copies.^[80][81]

Due to the album's success, Daydream and its singles were respectively nominated in six categories at the 38th Grammy Awards.^[82] Carey, along with Boyz II Men, opened the event with a performance of "One Sweet Day".^[83] However, Carey did not receive any award, prompting her to comment "What can you do? I will never be disappointed again. After I sat through the whole show and didn't win once, I can handle anything."^[83] Following her awards ceremony disappointments, Carey opted to embark on the Daydream World Tour. It had seven dates, three in Japan and four throughout Europe.^[84] When tickets went on sale, Carey set records when all 150,000 tickets for her three shows at Japan's largest stadium, Tokyo Dome, sold out in under three hours, breaking the previous record held by The Rolling Stones.^[84]

With her following albums, Carey began to take more initiative and control with her music, and started infusing more genres into her work.^[85][86] For Butterfly, she sought to work with other producers and writers other than Afanasieff, such as Sean Combs, Q-Tip, Missy Elliott and Jean Claude Oliver and Samuel Barnes from Trackmasters.^[86] During the album's recording, Carey and Mottola separated, with Carey citing it as her way of achieving freedom, and a new lease on life.^[87] Aside from the album's different approach, critics took notice of Carey's altered style of singing, which she described as breathy vocals.^[88] Her new-found style of singing was met with mixed reception; some critics felt this was a sign of maturity, that she did not feel the need to always show off her upper range,^[89] while others felt it was a sign of her weakening and waning voice.^[90][91] The album's lead single, "Honey", and its accompanying music video, introduced a more overtly sexual image than Carey had ever demonstrated, and furthered reports of her freedom from Mottola.^[92] Carey believed that her image was not "that much of a departure from what I've done in the past [...] It's not like I went psycho and thought I would be a rapper. Personally, this album is about doing whatever the hell I wanted to do."^[92] Reviews for Butterfly were generally positive: Rolling Stone wrote, "It's not as if Carey has totally dispensed with her old saccharine, Houston-style balladry [...] but the predominant mood of 'Butterfly' is one of coolly erotic reverie."^[93] AllMusic editor Stephen Thomas Erlewine described Carey's vocals as "sultrier and more controlled than ever," and heralded Butterfly as one of her "best records and illustrates that Carey continues to improve and refine her music, which makes her a rarity among her '90s peers.'"^[94] The album was a commercial success, although not to the degree of her previous albums Mariah Carey, Music Box and Daydream.^[95]

Carey began developing other projects during the late 1990s.^[96] On April 14, 1998, Carey partook in the VH1 Divas benefit concert, where she sang alongside Aretha Franklin, Celine Dion, Shania Twain, Gloria Estefan, and Carole King.^[97] Carey had begun developing a film project All That Glitters, later re-titled to simply Glitter,^[98] and wrote songs for other projects, such as Men in Black (1997) and How the Grinch Stole Christmas (2000).^[96] After Glitter fell into developmental hell, Carey postponed the project, and began writing material for a new album.^[96] Sony Music executives wanted her to prepare a greatest hits collection in time for the holiday season.^[99] They wanted to release an album that featured her number one singles in the United States, and her international chart toppers on the European versions, without any new material, while Carey felt that a compilation album should reflect on her most personal songs, not just her most commercial.^[100] The album, titled #1's (1998), featured a duet with Whitney Houston, "When You Believe", which was included on the soundtrack for The Prince of Egypt (1998).^[100] #1's became a phenomenon in Japan, selling over one million copies in its opening week, making Carey as the only international artist to accomplish this feat.^[101] It sold over 3.25 million copies in Japan after only the first three months, and holds the record as the best-selling album by a non-Asian artist.^[101]

During the spring of 1999, Carey began working on the final album per her record contract with Sony.^[102] However, due to the pressure and the awkward relationship Carey had developed with Sony, she completed the album in a period of three months in the summer of 1999, quicker than any of her other albums.^[103] Titled Rainbow (1999), the album found Carey once again working with a new array of music producers and songwriters, such as Jay-Z and DJ Clue?.^[104] Carey also wrote two ballads with David Foster and Diane Warren, whom she used to replace Afanasieff.^[104] Rainbow was released on November 2, 1999, to the highest first week sales of her career at the time, however debuting at number two on the Billboard 200.^[105] In the meantime Carey's troubled relationship with Columbia grew, as they halted promotion after the album's first two singles.^[105] They felt Rainbow did not have any strong single to be released, whereas Carey wanted to release a ballad.^[105] This led to a very public feud, as Carey began posting messages on her website, telling fans inside information on the dispute, as well as instructing them to request "Can't Take That Away (Mariah's Theme)" on radio stations.^[106] Ultimately, the song was only given a very limited and low-promotion release.^[107] Critical reception of Rainbow was generally enthusiastic, with the Sunday Herald saying that the album "sees her impressively tottering between soul ballads and collaborations with R&B heavyweights like Snoop Doggy Dogg and Usher [...] It's a polished collection of pop-soul."^[108] Though a commercial success, Rainbow became Carey's lowest selling album to that point in her career.^[109]

After she received Billboard's Artist of the Decade Award and the World Music Award for Best-Selling Female Artist of the Millennium,^[110] Carey parted from Columbia and signed an estimated $100 million, five-album recording contract with Virgin Records America (EMI Records) in April 2001.^[111][112] Carey was given full conceptual and creative control over the project.^[112] She opted to record an album partly mixed with 1980s influenced disco and other similar genres, in order to go hand-in-hand with the film's setting.^[113] She often stated that Columbia had regarded her as a commodity, with her separation from Mottola exacerbating her relations with label executives. Just a few months later, in July 2001, it was widely reported that Carey had suffered a physical and emotional breakdown. She had left messages on her website that complained of being overworked,^[114] and her three-year relationship with the singer Luis Miguel ended.^[115] In an interview the following year, she said, "I was with people who didn't really know me and I had no personal assistant. I'd do interviews all day long and get two hours of sleep a night, if that."^[116] Due to the pressure from the media, her heavy work schedule and the split from Miguel, Carey began posting a series of disturbing messages on her official website, and displayed erratic behavior on several live promotional outings.^[117] On July 19, 2001, Carey made a surprise appearance on the MTV program Total Request Live (TRL).^[118] As the show's host Carson Daly began taping following a commercial break, Carey came out pushing an ice cream cart while wearing a large men's shirt, and began a striptease, in which she shed her shirt to reveal a tight yellow and green ensemble.^[118] While she later revealed that Daly was aware of her presence in the building prior to her appearance, Carey's appearance on TRL garnered strong media attention.^[117] Only days later, Carey began posting irregular voice notes and messages on her official website: "I'm trying to understand things in life right now and so I really don't feel that I should be doing music right now. What I'd like to do is just a take a little break or at least get one night of sleep without someone popping up about a video. All I really want is [to] just be me and that's what I should have done in the first place ... I don't say this much but guess what, I don't take care of myself."^[118] Following the quick removal of the messages, Berger commented that Carey had been "obviously exhausted and not thinking clearly" when she posted the letters.^[119]

On July 26, she was suddenly hospitalized, citing "extreme exhaustion" and a "physical and emotional breakdown."^[120] Carey was admitted to an undisclosed hospital in Connecticut, and remained hospitalized and under doctor's care for two weeks, followed by an extended absence from the public.^[120] Following the heavy media coverage surrounding Carey's publicized breakdown and hospitalization, Virgin Records America and 20th Century Fox delayed the release of both Glitter, as well as its soundtrack of the same name.^[119][121] When discussing the project's weak commercial reaction, Carey blamed both her frame of mind during the time of its release, its postponement, as well as the soundtrack having been released on September 11.^[122] Critics panned Glitter, as well as its accompanying soundtrack; both were unsuccessful commercially.^[123] The accompanying soundtrack album, Glitter, became Carey's lowest-selling album to that point. The St. Louis Post-Dispatch dismissed it as "an absolute mess that'll go down as an annoying blemish on a career that, while not always critically heralded, was at least nearly consistently successful."^[124] Following the negative cloud that was enveloping Carey's personal life at the time, as well as the project's poor reception, her $100 million five-album record deal with Virgin Records America (EMI Records) was bought out for $50 million.^[112][125] Soon after, Carey flew to Capri, Italy for a period of five months, in which she began writing material for her new album, stemming from all the personal experiences she had endured throughout the past year.^[117] Carey later said that her time at Virgin was "a complete and total stress-fest [...] I made a total snap decision which was based on money and I never make decisions based on money. I learned a big lesson from that."^[126] Later that year, she signed a contract with Island Records, valued at more than $24 million,^[127] and launched the record label MonarC. To add further to Carey's emotional burdens, her father, with whom she had little contact since childhood, died of cancer that year.^[128]

In 2002, Carey was cast in the independent film, WiseGirls, alongside Mira Sorvino and Melora Walters, who co-starred as waitresses at a mobster-operated restaurant. It premiered at the Sundance Film Festival, and received generally negative critical response, though Carey's portrayal of the character was praised; Roger Friedman of Fox News referred to her as "a Thelma Ritter for the new millennium," and wrote, "Her line delivery is sharp and she manages to get the right laughs."^[129] Later that year, Carey performed the American national anthem to rave reviews at the Super Bowl XXXVI at the Louisiana Superdome in New Orleans, Louisiana.^[130] Towards the end of 2002, Carey released her next studio album Charmbracelet, which she said marked "a new lease on life" for her.^[116] Though released in the wake of Glitter and Carey's return to the music scene, sales of Charmbracelet were moderate and the quality of Carey's vocals came under criticism. Joan Anderson from The Boston Globe declared the album "the worst of her career, and revealed a voice [that is] no longer capable of either gravity-defying gymnastics or soft coos,"^[131] while AllMusic editor Stephen Thomas Erlewine expressed similar sentiments and wrote, "What is a greater problem is that Mariah's voice is shot, sounding in tatters throughout the record. She can no longer coo or softly croon nor can she perform her trademark gravity-defying vocal runs."^[132]

In April 2003, Carey announced she would be touring later in the year.^[133] The Charmbracelet World Tour: An Intimate Evening with Mariah Carey, spanned North America and East Asia over three months, generally playing in smaller venues rather than arenas.^[134] Throughout the United States, the shows were done in theaters, and something more Broadway-influenced, "It's much more intimate so you'll feel like you had an experience. You experience a night with me."^[133] However, while smaller productions were booked throughout the tour's stateside leg, Carey performed at stadiums in Asia and Europe, performing for a crowd of over 35,000 in Manila, 50,000 in Malaysia, and to over 70,000 people in China.^[135] In the United Kingdom, it became Carey's first tour to feature shows outside London, booking arena stops in Glasgow, Birmingham and Manchester.^[136] The tour garnered generally positive reviews from music critics and concert goers, with many complimenting the quality of Carey's live vocals, as well as the production as a whole.^[137]

Throughout 2004, Carey focused on composing material for her tenth studio album, The Emancipation of Mimi (2005). The album found Carey working predominantly with Jermaine Dupri, as well as Bryan-Michael Cox, Manuel Seal, The Neptunes and Kanye West.^[138] The album debuted atop the charts in several countries, and was warmly accepted by critics. Caroline Sullivan of The Guardian defined it as "cool, focused and urban [... some of] the first Mariah Carey tunes in years which I wouldn't have to be paid to listen to again,"^[139] while USA Today's Elysa Gardner wrote, "The ballads and midtempo numbers that truly reflect the renewed confidence of a songbird who has taken her shots and kept on flying."^[140] The album's second single, "We Belong Together", became a "career re-defining"^[141] song for Carey, at a point when many critics had considered her career over.^[142] Music critics heralded the song as her "return to form,"^[143] as well as the "return of The Voice,"^[143] while many felt it would revive "faith" in Carey's potential as a balladeer.^[138] "We Belong Together" broke several records in the United States and became Carey's sixteenth chart topper on the Billboard Hot 100.^[144] After staying at number one for fourteen non-consecutive weeks, the song became the second longest running number one song in US chart history, behind Carey's 1996 collaboration with Boyz II Men, "One Sweet Day".^[144] Billboard listed it as the "song of the decade" and the ninth most popular song of all time.^[145] Besides its chart success, the song broke several airplay records, and according to Nielsen BDS, gathered both the largest one-day and one-week audiences in history.^[146]

During the week of September 25, 2005, Carey set another record, becoming the first female to occupy the first two spots atop the Hot 100, as "We Belong Together" remained at number one, and her next single, "Shake It Off" moved into the number two spot (Ashanti had topped the chart in 2002 while being a "featured" singer on the number two single).^[144] On the Billboard Hot 100 Year-end Chart of 2005, the song was declared the number one song, a career first for Carey.^[147] Billboard listed "We Belong Together" ninth on The Billboard Hot 100 All-Time Top Songs and was declared the most popular song of the 2000s decade by Billboard.^[148]

The Emancipation of Mimi earned ten Grammy Award nominations: eight in 2006 for the original release (the most received by Carey in a single year),^[149] and two in 2007 for the Ultra Platinum Edition (from which "Don't Forget About Us" became her seventeenth number-one hit). Carey won Best Contemporary R&B Album and Best Female R&B Vocal Performance and Best R&B Song for "We Belong Together".^[149] The Emancipation of Mimi was the best-selling album in the United States in 2005, with nearly five million units sold. It was the first album by a solo female artist to become the year's best-selling album since Alanis Morissette's Jagged Little Pill in 1996.^[150] At the end of 2005, the IFPI reported that The Emancipation of Mimi had sold more than 7.7 million copies globally, and was the second-best-selling album of the year after Coldplay's X&Y.^{[151][152][153]} To date, The Emancipation of Mimi has sold over 12 million copies worldwide.^[154]

In support of the album, Carey embarked on her first headlining tour in three years, named The Adventures of Mimi after a "Carey-centric fan's" music diary.^[155] The tour spanned 40 dates, with 32 in the United States and Canada, two in Africa, and six in Japan.^[156] It received warm reception from music critics and concert goers, many of which celebrated the quality of Carey's live vocals, as well as the show as a whole.^[157][158] Carey played to about 60,000 fans in the two shows in Tunis.^[159] A live recording titled The Adventures of Mimi DVD was released in November 2007 internationally and December 2007 in the U.S.

By spring 2007, Carey had begun to work on her eleventh studio album, E=MC², in a private villa in Anguilla.^[160] Although E=MC² was well received by most critics,^[161] some of them criticized it for being very similar to the formula used on The Emancipation of Mimi.^[162] Two weeks before the album's release, "Touch My Body", the record's lead single, reached the top position on the Billboard Hot 100, becoming Carey's eighteenth number one and making her the solo artist with the most number one singles in United States history, pushing her past Elvis Presley into second place according to the magazine's revised methodology.^[163] Carey is second only to The Beatles, who have twenty number-one singles. Additionally, it gave Carey her 79th week atop the Hot 100, tying her with Presley as the artist with the most weeks at number one in the Billboard chart history."^[164]

The film garnered mostly positive reviews from critics, also for Carey's performance.^[174] Variety described her acting as "pitch-perfect."^[175] In January 2010, Carey won the Breakthrough Actress Performance Award for her role in Precious at the Palm Springs International Film Festival.^[176] On September 25, 2009, Carey's twelfth studio album, Memoirs of an Imperfect Angel, was released. Reception for the album was mostly mixed; Stephen Thomas Erlewine of AllMusic called it "her most interesting album in a decade,"^[177] while Jon Caramanica from The New York Times criticized Carey's vocal performances, decrying her overuse of her softer vocal registers at the expense of her more powerful lower and upper registers.^[178] Commercially, the album debuted at number three on the Billboard 200, and became the lowest-selling studio album of her career.^[179] The album's lead single, "Obsessed",^[180] debuted at number eleven and peaked at number seven on the chart, and became Carey's 27th US top-ten hit, tying her with Elton John and Janet Jackson as the fifth most top-ten hits.^[180] The album's follow-up single, a cover of Foreigner's "I Want to Know What Love Is", managed to break airplay records in Brazil. The song spent 27 weeks atop the Brasil Hot 100 Airplay, making it the longest running song in the chart's history.^[181]

The lead single, "Beautiful" featuring singer Miguel, was released on May 6, 2013, and peaked at number 15 on the Hot 100.^[214] Carey taped a performance of "Beautiful" along with a medley of her greatest hits on May 15, 2013; the taping aired on the American Idol finale the following day.^[215] On October 14, 2013, Carey announced that the album's former title track has been chosen as the second single; it premiered via Facebook on November 11, 2013. During a Q&A session following the song's release, Carey gave an update about the album, stating: "Now I've been inspired to add two more songs, so we're almost there.

Four stops included shows in South Africa.^[230] The tour grossed 30.3 million dollars.^[231]

On March 15, 2016, Carey announced that she was filming Mariah's World, a docu-series for the E! network documenting her Sweet Sweet Fantasy tour and her wedding planning process. Carey told The New York Times, "I thought it would be a good opportunity to kind of, like, show my personality and who I am, even though I feel like my real fans have an idea of who I am... A lot of people have misperceptions about this and that."^[232] The series premiered on December 4, 2016.^[233] Carey guest starred on the musical drama Empire, as a superstar singer named Kitty and sung the song "Infamous" featuring Jussie Smollett.^[234] On December 5, 2016, Carey participated in the VH1 Divas Holiday: Unsilent Night benefit concert, alongside Vanessa Williams, Chaka Khan, Patti Labelle, and Teyana Taylor.^[235] On December 31, 2016, Carey's performance on Dick Clark's New Year's Rockin' Eve in Times Square received worldwide attention after technical difficulties caused Carey's in-ear monitors to malfunction, resulting in what The New York Times referred to as a "performance train wreck."^[236] The singer cited her inability to hear the music without in-ear auditory feedback as the cause for the mishap.^[237] Carey's representatives and Dick Clark Productions placed blame on each other.^[238]

On February 3, 2017, Carey released the single "I Don't" featuring YG.^[239] Later that month, she voiced the Mayor of Gotham City in the animated film The Lego Batman Movie.^[240] In April 2017, it was announced that Carey is launching her own record label, Butterfly MC Records, a joint partnership with Epic Records.^[241] In July 2017, Carey made a cameo in the comedy film Girls Trip, starring Queen Latifah, Jada Pinkett Smith, and Regina Hall.^[242] The same month, Carey embarked on a tour with Lionel Richie, titled, All the Hits Tour.^[243] Carey was also featured in the official remix for French Montana's single "Unforgettable", alongside Swae Lee.^[244] In October 2017, she released a new soundtrack single, "The Star", for the movie of the same name.^[245] Carey also developed an animated Christmas film, titled Mariah Carey's All I Want For Christmas Is You, for which she recorded an original song called "Lil' Snowman." The film was released direct-to-video on November 14, 2017.^[246][247] In the same month, the singer resumed her All I Want for Christmas Is You, a Night of Joy and Festivity concert series, which for the first time visited other countries including England and France.^[248] On December 31, 2017, the singer returned to perform on Dick Clark's New Year's Rockin' Eve after the technical difficulties that hindered her previous performance, in what The New York Times described as a "made-for-television act of pop culture redemption".^[249]

In 2018, Carey signed a worldwide deal with Live Nation Entertainment.^[250] The first commitment out of the deal was her new Las Vegas residency, The Butterfly Returns, which was launched in July 2018 to critical acclaim.^[251][252] Its first 12 shows in 2018 grossed $3.6 million, with dates later extending into 2019 and 2020.^[253] Following the residency, Carey embarked on her Mariah Carey: Live in Concert tour in Asia and returned to Europe with her All I Want for Christmas Is You concert series.^[254][255] While on tour, a representative from Sony Music Asia Pacific presented Carey with a certificate for achieving 1.6 billion sales units in Asia Pacific.^[256] She also released professional live footage of her performance of "All I Want For Christmas Is You" during one of her European Christmas tour shows on YouTube.^[257]

In September 2018, Carey announced plans to release her fifteenth studio album later in the year.^[258][259] The project was announced alongside the release of a new song titled "GTFO",^[260] which she performed on September 21, 2018, when she headlined the 2018 iHeartRadio Music Festival.^[261] The album's lead single, "With You", was released in October and performed for the first time at the American Music Awards of 2018.^[262] The single became Carey's highest-charting non-holiday song on the US Adult Contemporary chart since "We Belong Together",^[263] and the third highest-charting song of her career on the Adult R&B Songs chart.^[264] The album, titled Caution, was released on November 16, 2018, and received universal acclaim from critics.^[265] Caution was described as a "fine-tuning" of Carey's previous work^[266] and was praised for its freshness which made it "pleasingly defiant."^[267] By December 2018, the album had been featured on numerous year-end lists by music critics and publications.^[268] In February 2019, Carey commenced the Caution World Tour in support of the album.^[269] Reviewing the singer's three-day residency at the Royal Albert Hall, Michael Cragg from The Guardian described Carey's "incredible, playful performances" as a testament to her status as a "gold-plated pop diva".^[270] Similarly, Kate Solomon from The Daily Telegraph acclaimed the shows as being a "a surreal but wildly enjoyable showcase of a brighter, more fun side of the pop icon".^[271]

Declining offers to appear in commercials in the United States during her early career, Carey was not involved in brand marketing initiatives until 2006, when she participated in endorsements for Intel Centrino personal computers and launched a jewelry and accessories line for teenagers, Glamorized, in American Claire's and Icing stores.^[272] During this period, as part of a partnership with Pepsi and Motorola, Carey recorded and promoted a series of exclusive ringtones, including "Time of Your Life".^[273] She signed a licensing deal with the cosmetics company Elizabeth Arden, and in 2007, she released her own fragrance, "M."^[274] The Elizabeth Arden deal has netted her $150 million.^[275] In 2007, Forbes named her as the fifth richest woman in entertainment, with an estimated net worth of US$270 million.^[276][277] In November 2011, it was reported that Carey's net worth was valued at more than $500 million.^[278][202] Business Insider estimates her net worth to be valued at more than $520 million, as of October 2018.^[279] On November 29, 2010, she debuted a collection on HSN, which included jewelry, shoes and fragrances.^[280]

Carey is a philanthropist who has been involved with several charitable organizations.^[281] She became associated with the Fresh Air Fund in the early 1990s, and is the co-founder of a camp located in Fishkill, New York, that enables inner-city youth to embrace the arts and introduces them to career opportunities.^[281] The camp was called Camp Mariah "for her generous support and dedication to Fresh Air children," and she received a Congressional Horizon Award for her youth-related charity work.^[282] Carey also donated royalties from her hits "Hero" and "One Sweet Day" to charities.^[283] She is well-known nationally for her work with the Make-A-Wish Foundation in granting the wishes of children with life-threatening illnesses, and in November 2006 she was awarded the Foundation's Wish Idol for her "extraordinary generosity and her many wish granting achievements."^[284][285] Carey has volunteered for the Police Athletic League of New York City and contributed to the obstetrics department of New York Presbyterian Hospital Cornell Medical Center.^[286] A percentage of the sales of MTV Unplugged was donated to various other charities.^[286] In 2008, Carey was named Hunger Ambassador of the World Hunger Relief Movement.^[287] In February 2010, the song, "100%", which was originally written and recorded for the film, Precious,^[288] was used as one of the theme songs for the 2010 Winter Olympics, with all money proceeds going to Team USA.^[289] Carey is also known for being a supporter and advocate for the LGBT community, and was honored with the "Ally Award" at the 27th GLAAD Media Awards in May 2016. The award is presented to media figures who have "consistently used their platform to support and advance LGBT equality and acceptance".^[290] In December 2017, PETA rewarded Carey with the 'Angel for Animal's Award' for "encouraging families to adopt from their local shelter” in her animated Christmas film, titled Mariah Carey's All I Want For Christmas Is You. ^[291]

One of Carey's most high-profile benefit concert appearances was on VH1's 1998 Divas Live special, during which she performed alongside other female singers in support of the Save the Music Foundation.^[97] The concert was a ratings success, and Carey participated in the Divas 2000 special.^[97] In 2007, the Save the Music Foundation honored Carey at their tenth gala event for her support towards the foundation since its inception.^[292][293] She appeared at the America: A Tribute to Heroes nationally televised fundraiser in the aftermath of the September 11 attacks, and in December 2001, she performed before peacekeeping troops in Kosovo.^[294] Carey hosted the CBS television special At Home for the Holidays, which documented real-life stories of adopted children and foster families.^[295] In 2005, Carey performed for Live 8 in London^[296] and at the Hurricane Katrina relief telethon "Shelter from the Storm."^[297] In August 2008, Carey and other singers recorded the charity single, "Just Stand Up" produced by Babyface and L. A. Reid, to support Stand Up to Cancer.^[298]

In 2008, Carey performed in a New Year's Eve concert for the family of Libyan dictator Muammar Gaddafi, something she later claimed to "feel horrible and embarrassed to have participated in."^[299] In March 2011, Carey's representative Cindi Berger stated that royalties for the song "Save The Day", which was written for her fourteenth studio album, would be donated to charities that create awareness to human rights issues to make amends for the Gadaffi error. Berger also said that "Mariah has and continues to donate her time, money and countless hours of personal service to many organizations both here and abroad."^[283] "Save The Day" was never released.

In 2013, human rights activists criticized Carey for performing in a concert for Angola's "father-daughter kleptocracy" and accused her of accepting "dictator cash."^[300]

In January 2019, Carey controversially performed in Saudi Arabia. In the United Kingdom, Owen Jones of The Guardian found her agreement to perform there questionable as "Carey has famously always had a devoted gay fanbase: in Saudi Arabia, homosexuality is punishable by death."^[301] Prior to this, Carey was under pressure to cancel this performance not only because of the murder of the journalist Jamal Khashoggi, but also because of the country's imprisonment of women's rights activists.^[302] In a statement to the Associated Press, Carey's publicist stated that when “presented with the offer to perform for an international and mixed gender audience in Saudi Arabia, Mariah accepted the opportunity as a positive step towards the dissolution of gender segregation. [...] As the first female international artist to perform in Saudi Arabia, Mariah recognizes the cultural significance of this event and will continue to support global efforts towards equality for all.”^[303]

Carey has said that from childhood she has been influenced by Billie Holiday, Stevie Ray Vaughan, and R&B and soul musicians such as Al Green, Stevie Wonder, Gladys Knight and Aretha Franklin.^[304] Her music contains strong influences of gospel music, and she credits the Clark Sisters, Shirley Caesar and Edwin Hawkins as the most influential in her early years.^[304] When Carey incorporated hip hop into her sound, speculation arose that she was making an attempt to take advantage of the genre's popularity, but she told Newsweek, "People just don't understand. I grew up with this music."^[305] She has expressed appreciation for rappers such as the Sugarhill Gang, Eric B. & Rakim, the Wu-Tang Clan, The Notorious B.I.G. and Mobb Deep, with whom she collaborated on the single "The Roof (Back in Time)" (1998).^[306] Carey was heavily influenced by Minnie Riperton, and began experimenting with the whistle register due to her original practice of the range.^[306]

During Carey's career, her vocal and musical style, along with her level of success, has been compared to Whitney Houston, who she has also cited as an influence,^[307] and Celine Dion. Carey and her peers, according to Garry Mulholland, are "the princesses of wails [...] virtuoso vocalists who blend chart-oriented pop with mature MOR torch song."^[308] Author and writer Lucy O'Brien attributed the comeback of Barbra Streisand's "old-fashioned showgirl" to Carey and Dion, and described them and Houston as "groomed, airbrushed and overblown to perfection."^[308] Carey's musical transition and use of more revealing clothing during the late 1990s were, in part, initiated to distance herself from this image, and she subsequently said that most of her early work was "schmaltzy MOR."^[308] Some have noted that unlike Houston and Dion, Carey writes and produces her own songs.^[309]

Love is the subject of the majority of Carey's lyrics, although she has written about themes such as racism, social alienation, death, world hunger, and spirituality. She has said that much of her work is partly autobiographical, but Time magazine wrote: "If only Mariah Carey's music had the drama of her life. Her songs are often sugary and artificial—NutraSweet soul. But her life has passion and conflict," applying it to the first stages of her career. He commented that as her albums progressed, so too her songwriting and music blossomed into more mature and meaningful material.^[310] Jim Faber of the New York Daily News, made similar comments, "For Carey, vocalizing is all about the performance, not the emotions that inspired it. Singing, to her, represents a physical challenge, not an emotional unburdening."^[311] While reviewing Music Box, Stephen Holden from Rolling Stone commented that Carey sang with "sustained passion," while Arion Berger of Entertainment Weekly wrote that during some vocal moments, Carey becomes "too overwhelmed to put her passion into words."^[312] In 2001, The Village Voice wrote in regards to what they considered Carey's "centerless ballads," writing, "Carey's Strawberry Shortcake soul still provides the template with which teen-pop cuties draw curlicues around those centerless [Diane] Warren ballads [.....] it's largely because of [Blige] that the new R&B demands a greater range of emotional expression, smarter poetry, more from-the-gut testifying, and less [sic] unnecessary notes than the squeaky-clean and just plain squeaky Mariah era. Nowadays it's the Christina Aguileras and Jessica Simpsons who awkwardly oversing, while the women with roof-raising lung power keep it in check when tune or lyric demands."^[313]

Carey's output makes use of electronic instruments such as drum machines,^[138] keyboards and synthesizers.^[314] Many of her songs contain piano-driven melodies,^[315] as she was given piano lessons when she was six years old.^[15] Carey said that she cannot read sheet music and prefers to collaborate with a pianist when composing her material, but feels that it is easier to experiment with faster and less-conventional melodies and chord progressions using this technique.^[15] While Carey learned to play the piano at a young age, and incorporates several ranges of production and instrumentation into her music, she has maintained that her voice has always been her most important asset: "My voice is my instrument; it always has been."^[95] Carey began commissioning remixes of her material early in her career and helped to spearhead the practice of recording entirely new vocals for remixes.^[316] Disc jockey David Morales has collaborated with Carey on several occasions, starting with "Dreamlover" (1993), which popularized the tradition of remixing R&B songs into house records, and which Slant magazine named one of the greatest dance songs of all time.^[317] From "Fantasy" (1995) onward, Carey enlisted both hip-hop and house producers to re-structure her album compositions.^[83] Entertainment Weekly included two remixes of "Fantasy" on a list of Carey's greatest recordings compiled in 2005: a National Dance Music Award-winning remix produced by Morales, and a Sean Combs production featuring rapper Ol' Dirty Bastard.^[318] The latter has been credited with popularizing the R&B/hip-hop collaboration trend that has continued into the 2000s, through artists such as Ashanti and Beyoncé.^[316] Combs said that Carey "knows the importance of mixes, so you feel like you're with an artist who appreciates your work—an artist who wants to come up with something with you."^[319]

Carey possesses a five-octave vocal range,^{[320][321][322]} and has the ability to reach notes beyond the 7th octave.^[323][324] Referred to as the "songbird supreme" by the Guinness World Records,^[309] she was ranked first in a 2003 MTV and Blender magazine countdown of the 22 Greatest Voices in Music, as voted by fans and readers in an online poll. Carey said of the poll: "What it really means is voice of the MTV generation. Of course, it's an enormous compliment, but I don't feel that way about myself."^[325] She also placed second in Cove magazine's list of "The 100 Outstanding Pop Vocalists."^[326]

Regarding her voice type, Carey said that she is an alto, though several critics have described her as a Coloratura soprano.^{[327][328][329]} The singer claims that she has nodules in her vocal cords since childhood, due to which she can sing in a higher register than others. However, tiredness and sleep deprivation can affect her vocals due to the nodules, and Carey explained that she went through a lot of practice to maintain a balance during singing.^[306][330]

Jon Pareles of The New York Times described Carey's lower register as a "rich, husky alto" that extends to "dog-whistle high notes."^[331] Additionally, towards the late 1990s, Carey began incorporating breathy vocals into her material.^[332] Tim Levell from the BBC News described her vocals as "sultry close-to-the-mic breathiness,"^[332] while USA Today's Elysa Gardner wrote "it's impossible to deny the impact her vocal style, a florid blend of breathy riffing and resonant belting, has had on today's young pop and R&B stars."^[333]

Sasha Frere-Jones of The New Yorker adds her timbre possesses various colors, saying, "Carey's sound changes with nearly every line, mutating from a steely tone to a vibrating growl and then to a humid, breathy coo. Her wide vocal range allows Carey to take melodies from alto bottom notes to coloratura soprano upper register."^[70] Carey also possesses a "whisper register." In an interview with the singer, Ron Givens of Entertainment Weekly described it this way, "first, a rippling, soulful ooh comes rolling effortlessly from her throat: alto. Then, after a quick breath, she goes for the stratosphere, with a sound that nearly changes the barometric pressure in the room. In one brief swoop, she seems to squeal and roar at the same time."^[334]

Her sense of pitch is admired^[331] and Jon Pareles adds "she can linger over sensual turns, growl with playful confidence, syncopate like a scat singer... with startlingly exact pitch."^[331]

Carey's vocal style, as well as her singing ability, have significantly impacted popular and contemporary music. She has consistently been cited as one of the greatest and most influential vocalists of all time. As music critic G. Brown from The Denver Post wrote, "For better or worse, Mariah Carey's five-octave range and melismatic style have influenced a generation of pop singers."^[335] According to Rolling Stone, "Her mastery of melisma, the fluttering strings of notes that decorate songs like 'Vision of Love', inspired the entire American Idol vocal school, for better or worse, and virtually every other female R&B singer since the Nineties."^[336] Jody Rosen of Slate wrote of Carey's influence in modern music, calling her the most influential vocal stylist of the last two decades, the person who made rococo melismatic singing.^[337] Rosen further exemplified Carey's influence by drawing a parallel with American Idol, which to her, "often played out as a clash of melisma-mad Mariah wannabes. And, today, nearly 20 years after Carey's debut, major labels continue to bet the farm on young stars such as the winner of Britain's X Factor show, Leona Lewis, with her Generation Next gloss on Mariah's big voice and big hair."^[337] New York Magazine's editor Roger Deckker further commented that "Whitney Houston may have introduced melisma (the vocally acrobatic style of lending a word an extra syllable or twenty) to the charts, but it was Mariah—with her jaw-dropping range—who made it into America's default sound." Deckker also added that "Every time you turn on American Idol, you are watching her children."^[338] As Professor Katherine L. Meizel noted in her book, The Mediation of Identity Politics in American Idol, "Carey's influence not just stops in the emulation of melisma or her singing amongst the wannabe's, it's also her persona, her diva, her stardom which inspires them.... a pre-fame conic look."^[339]

In addition to her vocal ability, Carey has been credited for her role and impact as a songwriter and producer. Upon honoring her with the "Icon Award" at their eponymous awards ceremony in 2012, Broadcast Music, Inc. (BMI) described the singer's songwriting as having a "unique and indelible influence on generations of music makers".^[340] Jeffrey Ingold of Vice hailed Carey's lyricism as being "among the most verbose in pop music", praising her ability to convey "nuanced stories about love, loss, sex, race and abuse" within her songs.^[341] Reviewing a 2018 Genius Live event centered on the singer's artistry, Jeff Benjamin of Forbes stated that Carey's songwriting abilities were a "commonly overlooked" aspect of her musical legacy.^[342]

Numerous historians and social scientists have also credited Carey's outspokenness on her own multiracial heritage for facilitating public discourse surrounding race relations in the United States, as well as the advent of intersectional feminism, during the 1990s. As noted by Professor Michael Eric Dyson in his book, Between God and Gangsta Rap: Bearing Witness to Black Culture, Carey's "refusal to bow to public pressure" surrounding the nature of her ethnicity exposed "the messy, sometimes arbitrary, politics of definition and categorisation" and "the racial contradictions at the centre of contemporary pop music" at the time.^[343] Sika Dagbovie-Mullins of Florida Atlantic University further credited Carey as being a trailblazing "multiracial heroine", remarking upon her ability to both exploit and critique "the various manifestations of the mulatta stereotype" throughout her career.^[344]

Among the hip hop, pop, and R&B artists who have cited Carey as an influence are Aneeka,^[345] Ariana Grande,^[346] Britney Spears,^[347] Beyoncé,^[70] Celine Dion,^[348] Katy Perry,^[349] Lady Gaga,^[350] Bridgit Mendler,^[351] Christina Aguilera,^[352] Jessica Simpson,^[333] Rihanna,^[353] Grimes,^[354] Kelly Clarkson,^[355] Nelly Furtado,^[356] Bonnie McKee,^[357] Leona Lewis,^[358] Brandy Norwood,^[336] Pink,^[359] Mary J. Blige,^[360] Melanie Fiona,^[361] Missy Elliott,^[70] Sam Smith,^[362][363] Hikaru Utada,^[364] Regine Velasquez, Sarah Geronimo, Jake Zyrus^[365] Jordin Sparks,^[366] Justin Bieber,^[367] Jessica Sanchez,^[368] and Sandy.^[369]

According to Stevie Wonder: "When people talk about the great influential singers, they talk about Aretha, Whitney and Mariah. That's a testament to her talent. Her range is that amazing."^[370] Beyoncé credits Carey's singing and her song "Vision of Love" as influencing her to begin practicing vocal "runs" as a child, as well as helping her pursue a career as a musician.^[70] Rihanna has stated that Carey is one of her major influences and idol.^[353] Aguilera said in the early stages of her career that Carey was a big influence in her singing career and one of her idols.^[352] According to Pier Dominguez, author of Christina Aguilera: A star is made, Aguilera has stated how she loved listening to Whitney Houston, but it was Carey who had the biggest influence on her vocal styling. Carey's carefully choreographed image of a grown woman struck a chord with Aguilera. Her influence on Aguilera also grew from the fact that both are of mixed heritage.^[371] Philip Brasor, editor of The Japan Times, expressed how Carey's vocal and melismatic style even influenced Asian singers. He wrote that Japanese singer Hikaru Utada "sang what she heard, from the diaphragm and with her own take on the kind of melisma that became de rigueur in American pop after the ascendance of Mariah Carey."^[364]

In an article titled "Out With Mariah's Melisma, In With Kesha's Kick", writer David Browne of The New York Times discusses how the once-ubiquitous melisma pop style suddenly lost in favor of the now-ubiquitous autotune in which the former was heavily popularized by the likes of Mariah Carey and Whitney Houston. Browne had commented "But beginning two decades ago, melisma overtook pop in a way it hadn't before. Mariah Carey's debut hit from 1990, "Vision of Love", [set] the bar insanely high for notes stretched louder, longer and knottier than most pop fans had ever heard." Browne further added "A subsequent generation of singers, including Ms. Aguilera, Jennifer Hudson and Beyoncé, built their careers around melisma. (Men like Brian McKnight and Tyrese also indulged in it, but women tended to dominate the form.)"^[372]

On a cultural level, Carey is seen as being synonymous with the Christmas and holiday season due to the lasting impact and popularity of her song "All I Want for Christmas Is You ", as well as her 1994 album "Merry Christmas".^[373] The singer has been credited for turning the genre of Christmas music into a commercially viable format within the music industry, as well as a ubiquitous part of wider popular culture, so much so that she has been dubbed the "Queen of Christmas".^[374] The song is the 10th best-selling single of all time as of June 2019, with global sales of over 16 million copies and royalties exceeding $60 million.^[375] The album is credited as being the greatest selling Christmas album of all time.^[376] Both the song and album have been hailed as being "one of the few worthy modern additions to the holiday canon" by publications such as The New Yorker.^[377] Speaking to Vogue in 2015 about "All I Want For Christmas Is You", Elvis Duran stated that the song's appeal was based on the fact that it was "a modern song that could actually have been a hit back in the ’40's", praising its "timeless, classic quality".^[374] The success of the song, in particular, has led Carey to build what Billboard described as a "growing holiday mini-empire".^[378] The singer has released a children's book based on "All I Want for Christmas Is You" in 2015,^[379] which went on to sell over 750,000 copies; she later released an animated family film based on the book and song in 2017.^[380]

Commercially, Carey is credited for popularizing and redefining the practice of remixing within the music industry. In a 2019 article for MTV, Princess Gabbara hailed the singer as being "the queen of remixes", praising her ability to "satisfy pop, R&B, hip-hop, and EDM audiences" when doing so.^[381] Speaking to Billboard in 2019 for a profile of Carey's career, David Morales, who first collaborated with the singer on the Def Club Mix of her 1993 single "Dreamlover", commented on Carey's revolutionary role in the popularization of remixes: "Mariah opened up a whole other door, and not many people at that time were capable of that. When other big artists saw what I did with Mariah, they wanted that. She's how I got into the studio with Toni Braxton, Aretha Franklin, Seal and Donna Summer."^[381]

Carey is also credited for introducing R&B and hip hop into mainstream pop culture, and for popularizing rap as a featuring act through her post-1995 songs. Sasha Frere-Jones, editor of The New Yorker commented, "It became standard for R&B/hip-hop stars like Missy Elliott and Beyoncé, to combine melodies with rapped verses. And young white pop stars—including Britney Spears, Jessica Simpson, Christina Aguilera, and 'N Sync—have spent much of the past ten years making pop music that is unmistakably R&B." Moreover, Jones concludes that "[Carey's] idea of pairing a female songbird with the leading male MCs of hip-hop changed R&B and, eventually, all of pop. Although now anyone is free to use this idea, the success of The Emancipation of Mimi suggests that it still belongs to Carey."^[70] Judnick Mayard, writer of The Fader, wrote that in regarding of R&B and hip hop collaboration, "The champion of this movement is Mariah Carey." Mayard also expressed that "To this day ODB and Mariah may still be the best and most random hip hop collaboration of all time," citing that due to the record "Fantasy", "R&B and Hip-Hop were the best of step siblings."^[382] Kelefa Sanneh of The New York Times wrote, "In the mid-1990s Ms. Carey pioneered a subgenre that some people call the thug-love duet. Nowadays clean-cut pop stars are expected to collaborate with roughneck rappers, but when Ms. Carey teamed up with Ol' Dirty Bastard, of the Wu-Tang Clan, for the 1995 hit "Fantasy (Remix)", it was a surprise, and a smash."^[383] In a review of her Greatest Hits album, Devon Powers of PopMatters writes that "She has influenced countless female vocalists after her. At 32, she is already a living legend—even if she never sings another note."^[384]

Carey began dating Tommy Mottola while recording Music Box,^[385] and married him on June 5, 1993.^[103] After the release of Daydream and the success that followed, Carey began focusing on her personal life, which was a constant struggle at the time.^[386] Carey's relationship with Mottola began to deteriorate, due to their growing creative differences in terms of her albums, as well as his controlling nature.^[386] On May 30, 1997, the couple announced their separation,^[387] with their divorce finalized by the time Mottola remarried on December 2, 2000.^[388] Carey was in a three-year relationship with singer Luis Miguel from 1998 to 2001.^[115]

Carey met actor and comedian Nick Cannon while they shot her music video for her song "Bye Bye" on an island off the coast of Antigua.^[389] On April 30, 2008, Carey married Cannon in The Bahamas.^[390] At 35 weeks into her pregnancy, she gave birth to their fraternal twins, Moroccan and Monroe, on April 30, 2011^[391] via Cesarean section.^[392] Monroe is named after Marilyn Monroe; Moroccan is named after the Moroccan-decor room in Carey's apartment where Cannon proposed to her.^[393]

In August 2014, Cannon confirmed he and Carey had separated a few months earlier.^[394] He filed for divorce on December 12, 2014.^[395] It was finalized in 2016.^[396]

On January 21, 2016, Carey and Australian billionaire James Packer announced that they were engaged.^[397] By October, however, they had ended their engagement.^[398]

Carey is an active Episcopalian.^[399] She stated in 2006: "I do believe that I have been born again in a lot of ways. I think what I've changed are my priorities and my relationships with God. I feel the difference when I don't have my private moments to pray. ... I'm a fighter, but I learned that I'm not in charge. Whatever God wants to happen is what's going to happen. I feel like I've had endless second, third, fourth, fifth and sixth chances. It's by the grace of God I'm still here."^[400]

In April 2018, Carey opened up about her struggle with bipolar II disorder.^[401] She, self-reportedly, was diagnosed in 2001, but kept the diagnosis private. Recently, she has sought out treatment in the form of medication and therapy.^[401]

Throughout Carey's career, she has collected many honors and awards, including the World Music Awards' Best Selling Female Artist of the Millennium, the Grammy's Best New Artist in 1991, and Billboard's Special Achievement Award for the Artist of the Decade during the 1990s.^[402] In a career spanning over 20 years, Carey has sold over 200 million records worldwide, making her one of the biggest-selling artists in music history.^[403][404] Carey is ranked as the best-selling female artist of the Nielsen SoundScan era, with over 52 million copies sold.^[405][406] Carey was ranked first in MTV and Blender magazine's 2003 countdown of the 22 Greatest Voices in Music, and was placed second in Cove magazine's list of "The 100 Outstanding Pop Vocalists."^[326][407] Aside from her voice, she has become known for her songwriting. Yahoo Music editor Jason Ankeny wrote, "She earned frequent comparison to rivals Whitney Houston and Celine Dion, but did them both one better by composing all of her own material."^[408] According to Billboard magazine, she was the most successful artist of the 1990s in the United States.^[409] At the 2000 World Music Awards, Carey was given a Legend Award for being the "best-selling female pop artist of the millennium," as well as the "Best-selling artist of the 90s" in the United States, after releasing a series of albums of multiplatinum status in Asia and Europe, such as Music Box and Number 1's.^[407][410] She is also a recipient of the Chopard Diamond award in 2003, recognizing sales of over 100 million albums worldwide.^[411] Additionally, the Recording Industry Association of America (RIAA) lists Carey as the third-best-selling female artist, with shipments of over 63 million units in the US.^[412][413] In Japan, Carey has the top four highest-selling albums of all time by a non-Asian artist.^[414]

Carey has spent 79 weeks at the number-one position on Billboard Hot 100, the greatest number for any artist in US chart history.^[415] On that same chart, she has accumulated 18 number-one singles, the most for any solo artist (and second after The Beatles).^[416] Carey has also had three songs debut at the top of the Hot 100 chart.^[417] In 1994, Carey released her holiday album Merry Christmas has sold over 15 million copies worldwide, and is the best-selling Christmas album of all time.^{[71][72][418][419]} It also produced the successful single "All I Want for Christmas Is You", which became the only holiday song and ringtone to reach multi-platinum status in the US.^[420] In Japan, #1's has sold over 3,250,000 copies and is the best-selling album of all time in Japan by a non-Asian artist.^[421] Her hit single "One Sweet Day", which featured Boyz II Men, spent sixteen consecutive weeks at the top of Billboard's Hot 100 chart in 1996, setting the record for the most weeks atop the Hot 100 chart in history.^[406] After Carey's success in Asia with Merry Christmas, Billboard estimated Carey as the all-time best-selling international artist in Japan.^[422] In 2008, Billboard listed "We Belong Together" ninth on The Billboard Hot 100 All-Time Top Songs^[423] and second on Top Billboard Hot 100 R&B/Hip-Hop Songs.^[424] The song was also declared the most popular song of the 2000s decade by Billboard.^[148] In 2009, Carey's cover of Foreigner's song "I Want to Know What Love Is" became the longest-running number-one song in Brazilian singles chart history, spending 27 consecutive weeks at number-one.^[425] Additionally, Carey has had three songs debut at number-one on the Billboard Hot 100: "Fantasy", "One Sweet Day" and "Honey", making her the artist with the most number-one debuts in the chart's 52-year history.^[426] Also, she is the first female artist to debut at number 1 in the U.S. with "Fantasy".^[407] In 2010, Carey's 13th album and second Christmas album, Merry Christmas II You, debuted at No. 1 on the R&B/Hip-Hop Albums chart, making it only the second Christmas album to top that chart.
