OK I wasn't sure if that was it's intended purpose or there was another.
So I would have to have NIN under another main playlist in order for this to work. If NIN was the top of the tree it will play them. All of my playlist are group names at top of tree, then albums, then singles for each album. Then in another section there are my Top 40, New, Rock, Heavy Metal, etc. If I don't want for some reason a song or album under one of these to play I mark as 'Ignore as Child'?
