I have this really strange issue on my Nexus one. Using the default music player, bTunes and Mixzing the music will be playing and then suddenly it will just stop. The app doesn't crash or anything. All I have to do is press play again but it starts the song over. I have noticed that when it happens, the trackball lights up but there are no notifications. What is going on here? I found that doubletwist does not experience this issue. I am running the stock 2.1 that came on the phone. Any ideas?
