Don't know all the songs, but one of them is B.Lloyd's "Heavy". Its the song that goes something like "some base and some treble, you're a lightweight and this is heavy metal; this is crunch time, its time to lock and load, I'm a rock star I rock n' roll"....or somthing like that. "B.Lloyd" is Brandon Lloyd who plays for the Chicago Bears. He recorded the track with the help of the Phunk Junkeez.
He mentions the track and the game here: http://sports.espn.go.com/espnmag/story?id=3738888
You can hear the track under the music section of his site: http://www.blloyd.com/
Then a couple of the songs are by a group called Shootyz Groove -- I think there are three songs by them(?). One song is called "One", one song is called "More Fire" and I don't know the title of the third song. That's all I can recall without looking at my game booklet.
