Chaka Khan & Rufus "Ain't Nobody"

The directive Rufus gave to Warner Brothers was simple: the funky pop-R&B song "Ain't Nobody" must be the lead single on Rufus and Chaka Khan's Stompin' at the Savoy album, or else they would give the song to Michael Jackson and Quincy Jones for inclusion on Michael's Thriller album. Warner Brothers originally balked but ultimately dropped their objections and the song went on to become the band's signature tune.
