This just happened recently when I got the 2.2.1 firmware. When I'm playing music, the music will sometimes start partway through the song; i.e. it gets to the end of one song, starts to play the next halfway through. I thought I might have something weird enabled but went through settings and didn't see anything. Anyone else heard of this? Also, sorry if this is a common problem, I tried to search but didn't find anything.
