The Beasties dropped this master jam in the summer of 1998, back when release dates really mattered, and for a week or two it was all you heard, anywhere you went. It's the last of their big Nineties statements, with Mike D summing it up in the electro-boogie hit "Intergalactic": "I am known to do the wop!" The Beasties stir-fry all kinds of beats in their wok, from old-school hip-hop and head-checking punk to bossa nova and reggae, as they speak out in favor of break dancers, ravers, the Knicks, Boggle and Buddhist introspection. Lost classic: "I Don't Know," a Brazilian-flavored guitar ballad where Adam Yauch ponders reality with Japanese rocker Miho Hatori.

“Help Me”

Joni Mitchell wrote and recorded this song for her album Court and Spark, but she had to switch from her regular band to make the song sound exactly the way she wanted. "I had attempted to play my music with rock & roll players," she told Rolling Stone. "They’d laugh, 'Awww, isn't that cute? She's trying to teach us how to play.'" Mitchell switched to a jazz band, Tom Scott’s L.A. Express, and scored the biggest hit of her career in the process.
