I have a droid x running rubix 1.8.3. I use the napster app to play my music. When I use my bluetooth headset and press play/pause button with it, the music will start on both napster and the musicmod playlist. I can delete playlist but still seems to start music back up anyways. So the question is can I use titanium backup and freeze the app so it won't run? I don't use it anyways. I am just worried if the musicmod app is needed for system functions and phone will crash and won't boot.
