I will recommend buying this if you don't mind buying singles, and dislike mp3s, however, it is 7 dollars for only 3 songs and a video, so unless you really like cd quality, I would suggest just getting mp3s. But on to the single itself, this one is very good. If you're even considering buying this you should already own Amnesiac, so you'll already have Knives Out. Even so, it's a good song and qucikly sets a mood even though the single's pretty short. The reason that I bought this was for one song: Cuttooth. Absolutely splendid song, energetic yet but not loud, I always sing along, you should download this song and if you like it, get the single, but if you don't like it, it's not worth the money. The third song is Life in a Glasshouse (full length version), which is the same as the album version, except instead of the spacey sounds in the beginning, it has a trumpet intro which is nice. I actually prefer this version and it ends the cd nicely. There's one more thing on this cd: the Pyramid Song video. This is an absolutely superb video, one of the best I've ever seen, to compliment one of the best songs in my opinion ever written. However, it's easy to find in the same quality on the internet, so it's not that much of a bonus. But if you're debating whether to get this, the video adds that much more value since you can easily access it any time. Overall a very good single, but a little short for the price.
