Music jukebox via....Youtube?

Been enjoying Youtube's Music Discovery Project.  Type in an artist's name, get 50 songs mixed from that artist.  Wanted to listen to Tosca, no, not Puccini's Tosca, but the electronic / chill music group Tosca.

It's Youtube...so not exactly high-fidelity music, but it's a better alternative to say, Last.FM, Pandora or Slacker, if you want to listen to just the artist you picked.

Hint: If you like chill music, type in "Cafe del Mar" or, "artist:delerium", or, "artist:dorfmeister", or my favorite, "artist:moby".

I really like "propellerheads", too.
