e-dubble: “Rebuild”

The underrated Baltimore rapper (and former member of Young English) drops a slightly less fiery follow-up to his should-have-been-a-breakthrough single, “Changed My Mind.”

Wiz Khalifa, Big Sean and Curren$y: “Flowers”

Think of it as the anti-“Watch the Throne”: With a minimum of fuss and a maximum of chill, Khalifa and Co. have assembled an upcoming mix tape (whence this new track springs) chronicling their obsessions with weed and retro R&B, in that order.

Meat Puppets: “Smells Like Teen Spirit” (Nirvana cover)
