I agree with the two guys above me, it's just hardly anything special. It's a pretty good Radiohead record. Personally, I don't see in what area it contributes to their legacy.. it's almost what Radiohead would sound like if they are asleep while writing and recording. It's subconscious sounding, which makes it kind of.. glorified background music! Yes! I can use it for that.
Lotus Flower and Codex are pretty great Radiohead songs, and I like the first three tracks, very trippy stuff. However, 'Giving up the Ghost' and 'Seperator' are again, nice, but just not interesting at all. I'd rate the album a bit higher if it would've closed with a bit more intensity.
