So are these soup playlists that were created with jEmplode or just regular playlists? If they're soups, you may cause all kinds of weird problems for jEmplode (you may find that you start to get duplicates in your soups or things out of order). jEmplode depends on the known soup sort order (it uses a binary search to see if soups already contain each tune, so if it's out of its expected order, all bets are off). I've never actually TESTED what happens, but buyer beware on that one. Alternatively you can unattach the soup so it's not updated anymore (delete the "soup" tag from the advanced tags menu and resync)
