DLNA: can only see music in playlists

This DLNA thing is about to cause me to leap out a window. When I turn on DLNA, I can see all my sharing computers. I can see all the folders that are shared, Music, Pictures, Video, Playlists. I can browse Pictures, Video and even Playlists, but it will NOT open the Music folder. Opening it causes DLNA to eventually time out. Here's the kicker. If I put music in a playlist...pops right up. I'm thinking of putting all my music in a giant playlist.

This may not be only a phone problem. PS3 does the same thing...sometimes.
