AudioGlue - Searching for Similar Musical Artists

AudioGlue is an interesting new Flash tool for finding bands that you may not have known about. You search for a first band, and then can expand to see what other bands are similar in sound and/or content. I used it with Caedmon's Call, and the results were pretty good. I did not find any bands I did not know about yet, but I only went a few layers deep. Definitely worth checking out for those looking to fill their iPod further.
