I looked at the download website but couldn't decide if I wanted a new Radiohead album or not, for any price! :-)
Don't get me wrong; the earlier stuff they did was awesome (Pablo Honey, The Bends) but the later material had me skipping tracks. (Music going backwards and Thom moaning on about something or other...) Saying that, there ARE some tracks that did rock: Idioteque, Optimistic, Go to sleep, There There.
Anyway, what happens when you finish the download? What exactly do you get? Tracks in MP3 format that are locked to your computer so they can't be copied? I agree it's an unusual approach to release an album with!
