ATLANTA (AP) — Kanye West is playing a birthday party. But it’s not one of those gigs with the pointy hats, candy gift bags and a moon bounce. He will be one of the headliners at Birthday Bash 20 in Atlanta — put together by radio station WHTA. Other acts in the lineup include Ludacris, Wale, Future, B.o.B., and Big Boi. Past artists to perform at Birthday Bash have included Jay Z, Drake, Usher, Lil Wayne, T.I., and Chris Brown.
