i don't know exactly which commercial you are talking about but there are two Pontiac commercials that have songs by an artist named Citizen Cope. The first one is calle "Son's Gonna Rise" and the next song is called "Let the Drummer Kick." If you don't know of Citizen Cope then you should look him up. He instantly became one of my top favorite artists when i heard about him.
