My thoughts
I've been listening to a load of Radiohead recently and noticed it's not all sad like everyone says. They draw more negative emotions than just sadness into their songs like frustration in Just and My Iron Lung; anxiety/urgency in Idioteque; and mostly unease in several of their songs like Paranoid Android, Decks Dark, etc... I have a few lists of how I feel about some songs.

This is just all my opinions after extensive exploration of Radiohead's discography, trying to understand each song's mood. The only album I couldn't like no matter what was Pablo Honey, sorry but it's not for me
