I use "3" as my music player (love the widget and everything else about it). Often when I'm in the car, my audio out cable which runs to my auxiliary input gets jostled, causing my Droid to think I'm unplugging/plugging the cord in. Whenever this happens, it starts up the stock music player and starts playing music. Now I have two songs going at the same time (one playing on 3, the other playing on stock). It's annoying, and kind of a pain in the butt to switch into the music player and stop it while I'm driving. I'd like to be more focused on the road and not have to worry about this! Any suggestions are appreciated, let me know if I can clarify anything for you. (fyi - running Bugless Beast 0.4 on a Motorola Droid).
