Atlanta rapper and multi-instrumentalist B.o.B is back with a new single off his forthcoming Underground Luxury album.

The single, titled "All I Want," features B.o.B both rapping and singing over a slow-paced beat, laced with soaring strings and heavy drums. It's the second single he's released for Underground Luxury, with the 2 Chainz-assisted "Headband" being the first.

B.o.B said the album will be 2013's "best musical album," adding that he didn't mean offense to Jay Z or Kanye West, who dropped albums earlier this year. He's holding a listening session for the album this evening at the Apple store in SoHo, New York.
