I agree with Fro to an extent. It's very good from my point of view, but Fro described how sounds compared to Kid A, etc.
There are some review on different sites that say this sort of thing better than me. You get the feeling that Thom didn't really think about creating the song, but just tried to expand on an idea. But then again for a collection of songs that he's made on his laptop, waiting around in airports and places, it's excellent. The standouts for me are The Eraser, Black Swan, And it Rained All Night and Harrowdown Hill. These seem like proper songs more than the others (for example, Atoms for Peace just gets nowhere.) The Eraser builds on piano chords and Thom's voice is excellent. Harrowdown Hill is also noticeably voice-oriented. This album shows much more of Thom's voice; Cymbal Rush is the most instrumental. If you loved Kid A you'll probably like the Eraser.
Yeah I got it for my birthday, I knew I was getting it

Edited, it makes sense now.
