I felt like putting this under "stunning recordings". The Tron: Legacy soundtrack by Daft Punk.
So. Much. Bass.
It also has some amazing orchestral work combined with the electronica. Not a massive dynamic range, but better than most CDs released these days. Would be neat if they do a BD-Audio release, but I'm not holding my breath.
I've actually be looking forward to this soundtrack more than the movie. I was not let down. Except I wish the tracks were longer.
