Hi.

Extending Tony's post a bit:
If you want a playlist to play exactly _one_ random artist, while playing all the songs of that artist in random order, you can do this:

1. Upload the songs to your player
2. Create a playlist "1 random artist random songs" (or short: 1RARS)
3. Create one sub-playlist for each artist below that 1RARS playlist. This could be done most easily in jemplode: Just go to the "artists" soup view, select all sub-playlist, copy, select 1RARS, paste.
4. edit the 1RARS playlist's flags: always randomize, pick 1 item.
5. edit the flags of all sub-playlists (using group editing) to "always randomize"
   

This should do it. Each time you select the 1RARS playlist, one item of that playlist (one artist) is selected at random, and all contents of that item are then randomized.
