Musicovery is web2.0neato for finding new music

Biz sent me a link to musicovery.com the other day, and I was instantly intrigued by both the way you tell it to find stuff you want to hear (by your mood, rarity, era, and genre), as well as how it presents it to you (spacial links, sorta like a Mind Map).  I haven't got the chance to really use it for a while, but I did sign up and am planning on seeing if I score any new music as a result.  It looks promising...!
