Prince wrote this song to express his feelings for the jazz pianist and R&B vocalist Patrice Rushen, who caught his eye while she was doing some synth programming for Prince’s debut album. The teenage prodigy offered this song and “I Wanna Be Your Lover” to her but she declined to record either of them, so he cut them for his eponymous 1979 sophomore album. Five years later, Chaka Khan and producer Arif Mardin transformed the languorous slow jam into a hip-hop electro-funk workout. On the strength of Melle Mel’s rapid-fire rap and boasting a music video that featured Shabba Doo and Boogaloo Shrimp of Breakin’, the song became the biggest hit of Chaka Khan’s career winning the Grammy for Best R&B Song.
