I'm sick of my iPod playlists

I can listen to other people's playlist using Webjay, I should have the same option on my iPod.

Something like:

1. I upload my library (just the metadata) to a server
2. I define criteria for a playlist, e.g. # songs, preferred theme
3. Somebody mixes me a playlist using songs from #1 and meeting criteria of #2
4. I download said playlist to iTunes where I give it a listen
5. I bitch about said playlist and question each and every song
6. I give above feedback to playlist creator for their education, their reputation is adjusted accordingly
