Any chance we could hook into the seed playlist generator at
http://the.echonest.com/

There's a good API that could be used to add a 'seed' playback mode by right clicking.

I guess the biggest pitfall is that it's technically for non-commercial use, so it couldn't be included directly, but it'd be great to have a way that we could choose to hook it into EJ ourselves using our own API key. It's been generating some pretty solid playlists.

I agree with you CiXel. i already used such features on streamed radios. sure that would be great directly in ejukebox!
