Has anyone been using this? I think there's supposed to be more to it than I'm about to say, but it basically seems to be your basic last.fm recommendations limited to independent artists, which is pretty cool, right?! I quick browse through has highlighted loads and loads of bands I'd never heard of, plus a few I had (including DiS favs Internet Forever and Esben and The Witch).

You might need to refresh a few times to get it to work.
