OK so 'The King of Limbs' isn't my favorite Radiohead album BY FAR. To be honest, I was quite charmed by it when it came out, but now I only play the second half of it: Lotus Flower, Codex, Giving up the Ghost and Separator.
That said, the album is worth it alone for Codex. That song is just insanely great, insanely Radioheadish, insanely classic, insanely beautiful. I can't find the right words for that song, it's just amazing.
