Music Problems (I know what I'm doing, and it isn't working)
 

I ripped my copy of South Park Rally (I know it isn't a great game), and I'm trying to put my own music into it. It has 9 audio tracks and 2 data tracks. I did everything, selfbooted it, and the game plays fine. But on every level it plays the music starting at the first track, to the second, and so on (Instead of playing the single track that corosponds with the level). What do I need to do to get the music to play correctly? Please help!
