I had 1.1.4 JB on my iPod Touch previously but then after I added a certain album from my computer (not bought form iTunes Music Store) and I go to play it on my iPod it wouldn't play and consequently made all my other music not play either. It goes to the screen where it shows the album art, but the bar that shows progress doesn't move and the timer doesn't tick either. I restored back to 1.1.4 and it still doesn't work. But after removing the album from my iTunes library and syncing with my iPod again, everything works fine. Weird isn't it? Anyone got any suggestions?
