Also, and I know this is heresy, but if you have any iTunes purchased Protected AACs, PM won't play them, and sometimes won't advance to the next track.
Pure music glitch?
I have pure music installed on my mac mini. Everything goes well until it won't play the next song. It shows up on my itouch, but just won't play. I have to close the pure music app and then restart it. It will then play for awhile{ 20-30 min} then does it again. Anybody else have these problems?
