Ghostface Killah is so charismatic, he can brag about being an old coot and make it sound badass. "New rappers need to skip town/This is East Coast music, Grandpa Ghost is around!" Ghost, now 40, raps. His ninth album is a return to gritty form after an uneven 2009 R&B experiment, Ghostdini: On track after track, he blows dust off some dirty-soul loop, with boasts as inspired as ever ("Catch me in a little hut in Benin, village-style, feeding the children") and street-crime storytelling as vivid as ever ("It was the night before he got popped/Big jars of haze, Cheech and Chong bong in the spot/Tropicana, strawberries, diced bananas . . ."). Get the guy a "Hip-Hop's #1 Grandpa" T-shirt.

“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.
