I have noticed 3 possible behaviors by the Karma when playing my MP3 collection in a playlist:

1. Track plays like normal
2. Track starts out paused - the track appears that it should be playing, but it is paused with the pause icon present. When I press the joystick up to play it plays normally. Annoying because the music stops in the middle of the playlist.
3. Similar to #2, but when pressing joystick up to play the track, it skips to the next track. All the ID tag info is displayed normally in all cases.

I am using the 1.11 firmware, and I know that the tracks in question are from questionable sources (online), but they play just fine on my computer with Winamp, Musicmatch, WMP, etc. Is there a certain encoder that Karma does not like? I'll have to dig deeper and find out what encoder was used on the problem tracks. Or is this a known bug?
