I think I listen to Radiohead too much. Haha. My favorite album is In Rainbows (I think this is the only album I found where from start to finish all of the song is just perfect).
Although, currently I listen to the more depressing song of them, like No Surprises, How To Disappear Completely, Pyramid Song, and Daydreaming. I don't know, maybe it's because I've been slightly depressed and just feeling not fit lately.
