Ain't No Other Man

"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 fifth 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 1930s and 1940s 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.

Released in June 2006 (see 2006 in music), the song reached Top 10 in several countries; becoming the most successful single from Back to Bacics and one of the most successful singles of the year, as well as peaking at number 6 in the United States. The song is Aguilera's first top-ten since "Beautiful" (2002). The single was Top 10 in more than 20 countries. To date, it has sold more than 4.5 million digital copies worldwide, including 1.7 million in the United States alone.

A music video for the song was directed by Bryan Barber. The video jumps back in time, where Aguilera becomes a jazz-era blues singer who, after a world tour, returns to her hometown juke joint. She has a lot of lost time to make up, and not just with the local press and her girlfriends, who populate her backstage and dressing-room scenes. The video also received positive reviews. Aguilera promoted the track in a series of performances, including 2006 MTV Movie Awards and 2007 Muz-TV Music Awards, and included the song on the setlist of her Back to Basics Tour and on its DVD: Back to Basics: Live and Down Under. The song received covers of various artists, including Jordin Sparks, Raquel Castro, Amelia Lily, Kara DioGuardi and Adam Lambert.
