I also have this problem on the Touch and noticed it happens when I lose signal. It usually happens after I flash a new rom, but it eventually goes away.

At some point after I start using a new rom, I get notification errors on boot up and use Memmaid to delete all my notifications. I think this usually coincides with the time when the music problem stops. I just had to do that today, so I'll get to test out my theory on the way home.
