The playlist mode has a bug where it deletes entries suddenly. I've one list with around 16 songs, but suddenly only the first 9 were left. Another bug is that there's no "Remove feom playlist" option, only "Delete" was there, and implied deleting the mudic file itself. Another problem is that the playlist order cannot be changed. Also, I've found the Search function to be incredibly weak, not finding songs I know are in my collection.
