Just recently, my Genius Mixes have started misbehaving. After the first song finishes, it plays again. When I skip it, the next song plays, then the first one again! I skip it, and it goes to the second one I've heard, which I then skip. Now I hear a new song, then we go back to the beginning to do it all over again! Anyone else seeing this kind of problem? I've had a hard time searching for it here and on the web in general because I'm not sure what terms to use. I have a 2nd gen iPod touch running iOS 4.2.1.
