Beer good! Napster bad! FIRE BAD!

Napster has opened their DRM-free MP3 store. Quick glance, it looks pretty cool. The store has an iTunes-esque interface, but it's all run in your browser with AJAX-y goodness. The selection looks good, too, so this might compete well with Amazon. I've already found a couple songs Amazon didn't have (Monster Magnet FTW!).
