The little vocal mumble interlude after the first chorus is beautiful and hard to describe. It's the affect it is sung with. I think Thom once said he thinks he could sing about something as meaningless as a toaster and someone would be brought to tears.
I do like Radiohead, but I'm sad they don't have more material like this. It (and everything off this album, really) seem much more original and moody, and there's BASS! =O But Kid A was pretty witty too.
