this has happened to me 3 or 4 times now:

I load all new songs into my system every few weeks, obviously some are repeats, but basically reload my entire playlist....

when i do that, everything works lovely....no issues

on a few songs, they work once or twice and after that, when I try to load them, the track loads on the screen, but the wav form is gray and the track wont play

is ssl accidentally corrupting these mp3s? when I reload the master again a couple weeks later it works fine. has anyone else had this problem? its not a huge deal, but it does mean I find that a song I wanted to play that night might not be working. am i doing something wrong?
