"Something" is a song by The Beatles featured on their 1969 album Abbey Road. It was also released as Double A-sided single with "Come Together". "Something" was the first Beatles song written by lead guitarist George Harrison to appear as an A-side, and the only song written by him to top the US charts while he was in the band.^{[citation needed]} The single was also one of the first Beatles singles to contain tracks already available on an LP album, as both songs appeared on Abbey Road.

John Lennon and Paul McCartney, the band's principal songwriters, both praised "Something" as among the best songs Harrison had written, or the group had to offer. As well as critical acclaim, the single achieved commercial success, topping the Billboard charts in the United States and making the top five in the United Kingdom. The song has been covered by over 150 artists, including Phish, Isaac Hayes, Elvis Presley, Ray Charles, Shirley Bassey, Ike & Tina Turner, Frank Sinatra, Tony Bennett, James Brown, Julio Iglesias, The Miracles, Eric Clapton, and Joe Cocker, and is the second-most covered Beatles song after "Yesterday". Harrison is quoted as saying that his favourite cover of the song was James Brown's, and he kept Brown's version in his personal jukebox.

Christina María Aguilera (born December 18, 1980) is an American recording artist and actress. Aguilera first appeared on national television in 1990 as a contestant on the Star Search program, and went on to star in Disney Channel's television series The Mickey Mouse Club from 1993 to 1994.

In 1999, Aguilera came to prominence following her debut album Christina Aguilera, which was a commercial success spawning three number one singles on the Billboard Hot 100—"Genie in a Bottle", "What a Girl Wants", and "Come On Over Baby (All I Want Is You)." 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.
