Prince wrote this song and released it on his second album, Prince, in 1979. It was Chaka Khan that had a hit with it! Her version uses more instrumentation and production elements than Prince’s original stripped-down original.
Her version also differed from the original in that it feature a rap segment. Chaka had no idea this song was . She hated it and couldn’t stand hearing her name repeated over and over in the song, but she was persuaded that it would make the song a hit.
The downside is that Chaka would from then on be confronted by people rapping her name in imitation of the song, which drove her nuts.
