I think it's slightly foolish to start ranking albums and songs less than a couple hours after owning this thing.
After one listen all I can say is that there are a few songs that suffer from a bit too much clutter. Obviously on headphones that's going to be magnified, but it reminded me of all the digital clutter in the Star Wars prequels, little bits of screwy business going on in the edges of the frame that are completely unnecessary. Sometimes these little things work, sometimes they don't. I think All I Need is phenomenal, but has some noises I could do without. From what I remember, House of Cards was a little cluttered as well. And Videotape...christ I'm glad I haven't heard all the versions you guys have or I'd probably be pissed off. What the fuck is that clomping drum sound?! And then that intermittent crap near the end that sounds like someone rapping on top of your stereo? Just wrong.
Lance mentioned Nigel, and I could have sworn I just read somewhere that he didn't work on this album. You guys would know more than I would, but if it's true his absence is telling.
Also, I agree with Lance in that I'm not sure if I like this better than Hail to the Thief. It's definitely more consistent, but that's not so hard when you're dealing with 15 songs instead of 10. I'm pretty sure, without looking, that the 10 best songs on HTTT would stack up pretty damn well against Rainbows, and for starters I'll take 2+2=5 and Sit Down Stand Up over 15 Step and Bodysnatchers.
This could very well be the album of the year, no doubt. But I feel that it could have been even better.
Oh yeah, for the record, you can add All I Need and Nude to that list of Radiohead songs that are more beautiful than How to Disappear.
