My mp3 player has been synced with windows media player 11 and when the mp3 player has been unplugged and refreshed, it showed 3125 songs, but when I plugged it back in and counted the songs, it showed 1895 songs. When I unplug it and turn it on and start playing songs, it says unsupported files and then shows some .alb files in the songns area. I need help with this option.
