"BBD" stands for "Bad Bitches Do It" – although Azealia Banks does give a nod and a wink to that other BBD, New Jack Swing heroes Bel Biv Devoe, shouting out group leader Michael Bivins. But the new track from the irrepressible Harlem rapper really is about bad bitches: a typically fleet, flashy collection of disses and boasts that glory in estrogen power, Sapphic delights, and the fun of cuckolding stupid dudes. ("Tits out with ya wife, nigga/I'm bringing out the dyke in her.") Great beat, too.

Listen to "BBD":

“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.
