What I really dislike with these players is the back button when in shuffle mode. It really should not shuffle backwards. There are so many times where I accidentally skip a song I want to listen to because I am flicking forward too fast. Then I press back, bam, it shuffles again. The most unusual aspect of this is that it SOMETIMES, not often, works and pressing back does in fact go back to previous song. But I haven't been able to find a pattern.
Really wish this was fixed as I can't really understand why anyone would want to shuffle backwards when its exactly the same as shuffling forward.
