Is there a website that works like a matchmaker of people with the same favorite music?

Question

I'm curious about whether I'd get along well with someone who just happened to like several hundred of the same songs as I.
Wouldn't it be a cool feature for a personals hookup site?
Scan the globe and see who in the world most exactly shares your taste in songs. A favorite color match might also be fun, since there's some psychology behind color.

Answer 1

Last.fm is a site that shows your songs on itunes (or other music player) and when you are logged on and go to another persons homepage, it shows you music compatability.
