I understand but using that system is too much work. I just want my media in a librart, pick the songs and sync the list. I change my music quite often and I can use my mobile phone, or clip+ without problems.
I find it quite strange that a player can miss a song off of a playlist because it is the first song but show it is you add it again as the 2nd song.
That is a problem Sanddisk need to correct though it is too late to keep me.
