Music Reccommendation Sites

A while back, I stumbled upon some site that would take an artist/band name and display it in a moving graph of sorts against other groups in a “If you like A, you’ll probably like B” sort of fashion. Supposively it was getting its information from folks (like you) entering in their likes and dislikes and yadda yadda… Anyway, does anyone know what the site was? Or for that matter, have a reccommendation for a decent site that does similar?

Is this the site you’re looking for?
I came up with this great idea for a music recommendation site, thought of a great name for it and everything. And then I see that it had already been done, gaddamnit.

oh, and Jophiel, tell Edamoth that Bethanna says hello…
