Either I am totaly missing something but l can't seem to see anywhere that says who added a playlist or even a music track. Also there is not a tab to display My playlists or tracks. I think this is important especially for moderating as you need to know who added the music. For instance what if a member added a track which was full off swearing or had racial tendensies, who would you know to warn or remove ? Yes you could delete the track but becuase you don't know who added it they would just add it again.
Thinks this needs to be looked at as is quite important.
