The OutKast MC's latest single rides an electro-funk groove so spry, Prince-ly and Eighties inspired that you can practically see Molly Ringwald roller-skating to it. Big Boi sounds typically light on his feet, speed-drawling comparisons between himself, Mozart and Van Gogh, while Kelly Rowland plays airy hook girl, reciting "Mama"'s practical advice. It's neon lit pop fun – a straightforward crowd pleaser from a rap hall of famer.

“1999”

“I don’t consider myself a great poet,” Prince told Rolling Stone. “I just know I’m here to say what’s on my mind.” In the case of the apocalyptic party anthem “1999,” he was worried about then-president Ronald Reagan’s foreign policies. The song’s melody is based on a riff borrowed from the Mamas and Papas’ “Monday, Monday,” and Prince originally envisioned the first verse with three-part harmony but later split the vocals between himself and members of the Revolution. Because Warner Bros., with whom Prince was locked in a contractual battle, owned the original’s masters, Prince rerecorded the song and appropriately released that version in 1999.
