Originally considered for Gladys Knight & the Pips and later for Diana Ross, as "I Wanna Be Free", "I Want You Back" explores the theme of a lover who decides that he was too hasty in dropping his partner. An unusual aspect about "I Want You Back" was that its main lead vocal was performed by a tween, Michael Jackson.
"I Want You Back" was released on October 6, 1969 and was the first Jackson 5 single to be released by Motown and the first song written and produced by The Corporation, a team comprising Motown chief Berry Gordy, Freddie Perren, Alphonso Mizell, and Deke Richards. It also is the first of four Jackson 5 number-ones released in a row (the others being "ABC" – 1970, "The Love You Save" – 1970, and "I'll Be There" – 1970) and the first Jackson 5 song recorded in Los Angeles, California; the quintet had previously been recording Bobby Taylor-produced remakes of other artists' hits, including "Who's Lovin' You", the B-side to "I Want You Back", at Hitsville U.S.A. in Detroit, Michigan. From late 1969 and on, nearly all of the Jackson 5's recordings were done in Los Angeles when the majority of recordings for other artists on the label were done in Detroit.
Although Gladys Knight had been the first to mention the Jacksons to Berry Gordy, and Bobby Taylor brought the Jackson brothers to Motown, Motown credited Diana Ross with discovering them. This was done not only to help promote the Jackson 5, but also to help ease Ross' transition into a solo career, which she began in 1970 soon after the Jackson 5 became a success.
The song was remixed for the 2009 release .
