Can somebody explain me why sometimes the left corner from the player (a or b) is lighted up. I have this with several songs. When I play the number it light up, play other number not, play first number again, not light up? Several moment later, play same number again, light up?
Also what is the meaning of the unsorted list. When I arrange a play list with numbers from the file archive, save list, load list in a player, these songs are now also in the unsorted list?
