B.o.B

Who: Prolific hip-hop prodigy that hipsters also love -- a SPIN pick for Who's Next.
Hometown: Atlanta
Why you should see him: "I'll Be in the Sky" is catchy-as-hell Southern hip-hop, just a shade less addictive than "Hey Ya." Plus, B.o.B -- who recently began going by his real name, Bobby Ray -- is a multi-instrumentalist who defies any number of rapper stereotypes.
