"Ain't No Other Man" is a song by American recording artist Christina Aguilera. It was released by RCA Records as the lead single from her third studio album Back to Basics (2006). It was written by Aguilera, Charles Roane, DJ Premier, Harold Beatty, and Kara DioGuardi and produced by Premier and Roane. After taking a career break and collaborating with different artists, Aguilera created a "jazz-influenced" album and worked with different producers. The song marked a change of musical style, scrapping her pop roots and using funk and soul elements, creating a throwback to the '30s and '40s sound.

Lyrically, the song talks about finding a true love and was inspired by Aguilera's former husband Jordan Bratman. Aguilera said that the song is not a love song and it's an upbeat, fun track. Critics positively commended the track, for the brash and fresh horns, its fun content and for her voice - some even wrote that it is at her best. It also has been noted as one of Aguilera's strongest singles and won the Grammy Award for Best Female Pop Vocal Performance at the 2007 ceremony.

Ain't No Other is the fourth album released by MC Lyte. It was released on June 22, 1993, on First Priority Music/Atlantic Records and produced by Audio Two, Backspin, Markell Riley, Franklin Grant, Tyrone Fyffe, "Lil" Chris Smith, Funk, Sir Scratch and Walter "Mucho" Scott. Ain't No Other slightly improved on the charts from her last album, peaking at #90 on the Billboard 200 and #16 on the Top R&B/Hip-Hop Albums and producing two charting singles "I Go On" which peaked at #27 on the Hot Rap Singles and the more successful "Ruffneck" which made it to #1 on the Hot Rap Singles, #35 on the Billboard Hot 100 and #25 on the Rhythmic Top 40.

Ain (French pronunciation: [ɛ̃]; Arpitan: En) is a department named after the Ain River on the eastern edge of France. Being part of the region Rhône-Alpes and bordered by the rivers Saône and Rhône, the department of Ain enjoys a privileged geographic situation. It has an excellent transport network (TGV, highways) and benefits from the proximity to the international airports of Lyon and Geneva.

Ain is composed of four geographically different areas (Bresse, Dombes, Bugey and Pays de Gex) which – each with its own characteristics – contribute to the diversity and the dynamic economic development of the department. In the Bresse agriculture and agro-industry are dominated by the cultivation of cereals, cattle breeding, milk and cheese production as well as poultry farming. In the Dombes, pisciculture assumes greater importance as does viticulture in the Bugey. The high diversification of the department's industry is accompanied by a strong presence of the plastics sector in and around Oyonnax (so-called "Plastics Valley").

Her sophomore and her debut Latin-pop album, Mi Reflejo (2000), a Christmas third studio album, My Kind of Christmas (2000), and several collaborations followed which garnered Aguilera worldwide success, though she was displeased with her lack of input in her music and image. After parting from her management, Aguilera took creative control over her fourth studio album, Stripped (2002). The album's second single, "Beautiful", was a commercial success and helped the album's commercial performance amidst controversy over Aguilera's image. Aguilera followed up Stripped with the soul, jazz and blues inspired, Back to Basics (2006), released to positive critical acclaim. The album produced three singles "Ain't No Other Man", "Hurt" and "Candyman". Four years later Aguilera released her sixth studio album, Bionic (2010), which incorporated aspects of R&B, electropop, and synthpop and was met with mixed reviews and low sales. Aguilera's seventh studio album is set to be released in 2012.
