Anyone know anyway to kill the music that automatically plays for games in your games list?

Specifically, I just downloaded the Cash, Money Chaos demo (or whatever it is) and it plays a LOUD annoying pop punk song whenever it's selected. It's also the first game in my demo list, right after whatever disc I have in the machine. So if I pop a disc out, it defaults to that and the music starts blasting.

Really fucking annoying.
