Remember the days of Tony Hawk, turning off the songs you hated and ending up with a mix of only the best tracks? That's kind of like what EA has done with SSX. With 46 songs on the disc, I think it'll be a while before we start messing around with custom soundtracks on the mountain.
We've slapped together the songs main soundtrack. There are three tacks missing from Youtube (including a TRS-80 track (TRS-80 is awesome by the way)) and there are 10 tracks that have been created specifically for SSX as part of the game's Deadly Descents. Fans of of dubstep will be happy to know that there is dubstep in the mix.
