Just moments ago, Big Sean released his first single, Guap, off his sophomore album, Hall of Fame: Memoirs of a Detroit Player. Produced by both Key Wane and Young Chop, they gave it an island feel. A different sound for Big Sean, but he did a good job over the beat. You can even hear a little Kanye West in the song. Take a listen, you might feel the sudden urge to bob your head to it. G.O.O.D Music!
