If its the one with rollerskates thats off the new Gorillaz album called Demon Days: Feel Good Inc. If its The other its Daft Punk's latest called Human After All.
:lol I remember that episode. Actually a lot of songs in SSX3 are becoming more mainstream in recent memory. For example the Jason Nevins remix of "Rockstar" headlined the Taxi soundtrack, as does MXPX's "Play It Loud" in Lords of Dogtown (whatever it's called).
