Glad you like the idea. Dynamic Playlists seemed an obvious and invaluable feature for the Rio.

I may have found a decent Java library to access ID3v2 tag info. If it works out, in a future release of JReceiver you'll be able to filter based upon any of the more advanced tags, such as 'composer'.

It should be possible to extend this to allow you to group together DPs under a new playlist name. This way the filter expressions for individual DPs could be kept small and comprehensible.

I wonder if the Audiotron could ever do this? ;^)
