Contributions to the album's production came from a wide range of producers, including Johan Åberg, David Frank, Ron Fair, Guy Roche, Robin Thicke, Matthew Wilder and Aaron Zigman.

Peiken also re-wrote with Roche the single version for the track "Come on Over", first produced by Johan Aberg, Paul Rein and Aaron Zigman.

"[10] Peiken co-wrote "Don't Make Me Love You", "Too Beautiful for Words", and "Dreamy Eyes", but those songs — though recorded — were scrapped, as the album only had space for twelve tracks.

"[14] Franne Golde (who previously worked with Whitney Houston) also wrote a song for Aguilera titled "So Emotional" which was originally written for Selena's album, but unfortunately she died at the age of 23.

The track's producer, Ron Harris, revealed that Aguilera in-between recordings "was only listening to Mariah Carey and Brandy, putting on her Walkman and practicing their riffs and runs, before she did her ad-libs.

[26] Billboard editor Kenneth Partridge wrote that the song features "32nd-note bass-drum pattern that mimics the heart palpitations of a teenager in lust.

The video includes interviews with her from backstage, in the studio and on the road, also featuring Aguilera's rendition of Mel Torme's Yuletide classic "The Christmas Song (Chestnuts Roasting on an Open Fire)".

[36] During late 2000, Aguilera traveled to Brazil to promote the album, where she did many interviews and performances on Brazilian television, including Domingão do Faustão, Programa Raul Gil and Planeta Xuxa.

It's designed with my band and dancers to be a visually exciting mix of my big hits and some special surprises", adding: "Plus, my sponsors, Sears and Levi's, are giving fans lots of ways to get involved with the tour, like exclusive CDs and posters, a chance to win a backstage pass to hang with me and a cause-related program called 'Come On Over and Do Something' that was created specifically for the tour.

"[38] One feature of the shows she described involved getting the crowd excited with her hit "What a Girl Wants" and then switching to a piano-and-vocal-only song by her idol, blues legend Etta James.

It topped the charts for five consecutive weeks on Billboard Hot 100 due to strong physical CD sales and airplay, having the longest stay at number one of 1999.

[49] Its music video was a success, becoming a staple on MTV's Total Request Live and featuring Aguilera enjoying some fun and sexual tension at a beach bonfire.

A version of the song in Spanish, entitled "Genio Atrapado", was recorded and included in some editions of Christina Aguilera and later on her Spanish-language album Mi Reflejo.

[53] Released on October 29, 1999, to radio stations,[54] the song received positive reviews from critics, with most praising her vocals on the track,[55] comparing them to those of Mariah Carey[6] and Whitney Houston.

It received mixed reviews from critics, who recognized that the track allowed Aguilera's vocals to soar and shine,[45] but called it a cliché ballad.

[62] The music video was directed by Joseph Kahn, and features Aguilera singing in front of a microphone before walking in the rain with an umbrella, and on a rooftop.

Canoe's Stephanie McGrath, Aguilera revealed plans to release at least two more singles from her debut–"Come On Over (All I Want Is You)" as soon as "I Turn to You" "runs its toll", and "So Emotional" that fall.

[10] "So Emotional" indeed had a simple music video, which was made available through Aguilera's Vevo account in 2009,[64] showing her in a casual outfit recording the song in the studio.

"[10] The reworked version, entitled "Come On Over Baby (All I Want Is You)", features more hip hop and dance elements as well as "edgy" and "sexual" lyrics,[53] even a rap by Aguilera.

[66] However, the song was a success on the charts, becoming Aguilera's third number-one hit on the US Billboard Hot 100, spending four weeks at the top, from October 8 to November 4, 2000.

"[20] Although calling it "a frustratingly erratic album", Beth Johnson wrote that "Christina still makes a credible bid to be the late-summer soundtrack to romantic rebound.

"[24] Sputnikmusic editor Amanda Murray wrote that Christina Aguilera "is an album that is highly representative of the better aspects of the teen pop movement of the late 90s.

"[70] Ann Powers on behalf of The New York Times agreed, writing: "Beyond its sleek design, this album hints at a real singer's emergence.

"[73] Barry Walters from Rolling Stone criticized the album's theme, calling it "bubble-brained", writing that they "give Aguilera little substance to spin into gold.

"[69] Julene Snyder of Sonicnet wrote that "Aguilera has an instinctive grasp of the insipid state of the pop/dance music scene, especially as it relates to her peers.

[74] Jason Lipshutz of Billboard cited her Grammy win as one of her "10 Biggest Career Moments", describing it as "the battle for teen pop supremacy" as Britney Spears and Christina Aguilera were both nominated for the Best New Artist prize.

Aguilera also received a Grammy nomination in 2001 for "What a Girl Wants" in the "Best Female Pop Vocal Performance" category, and according to Time magazine, "both of which helped catapult the album to the top of the charts".

In the United States, Christina Aguilera debuted at number one on the Billboard 200 with first-week sales of 252,800 copies, beating Puff Daddy's Forever.

[90] The album was certified octuple platinum by the Recording Industry Association of America (RIAA) for exceeding shipments of eight million copies.

[78] While listing the "100 Greatest Singers of All Time", Rolling Stone placed Aguilera at number 52, picking "Genie in a Bottle" as one of her "key tracks", writing that "Even in her teen-pop days, she was modeling her dramatic, melismatic technique on old-school soul heroines like Etta James".
