So I had 2 versions of Gallery and Music Player when I was running 2.0.1 and downloaded the apk's for the 2.1 Gallery and Music apps. When I upgraded to 2.1 OS I figured the 2.0 apps would be wiped out. It appears that they have until you look deeper. I have only one icon for the stock music app but noticed that when I press the button on my headset it would start and pause music OTHER than what was qeued in the music app. When I go to 'manage apps' I have 2 music apps listed (both say ver 7). One is 580kb and the other 4kb, giving the impression that the 4kb version is nothing really, but there are definately two versions running at times...hence the whole 2 different songs playing at once deal when I press the headset button. Any ideas? I'm reluctant to try deleting anything as I am not sure how I can verify that any of the files floating around right now for the music app are the current version and don't wanna complicate life if I delete something that causes a problem.
