"Take Me With U" (1985)
Though only the fifth biggest single off Purple Rain, the elegant, crystalline duet with Apollonia Kotero – originally intended for Apollonia 6's self-titled album – transcends both the album and the decade that birthed it. From the arresting drum-solo intro (which doubles as an equally stunning bridge) to the breathless exchanges between the two singers ("You're sheer perfection"; "Thank you."), the song instantly earned a place in the pantheon of classic love jams. "I don't have an expiration date," Prince said in an interview with The Word in 2004. "Take Me With U" is proof.
