Musical Relationships

Boing Boing pointed to a site called Music Plasma, which is a nifty little flash app which creates a visual relationship between the artist of your choosing and others that are related. No idea where they are getting their information, but it's very similar to what AudioGalaxy (if you remember them) had, as well as various other services which have a "others who have listened to this music also enjoyed...." link. Seems like a great way of searching for new artists to listen to though! Now this just needs to get integrated into MusicBrainz :)
