You run into a problem when you judge things only by how they sound on the surface without considering what's happening below. As I've said about 234908234908 times now to no response from any people who attack NLOTH, Crazy Tonight is a song about hedonism. The character is happily ignoring the rest of the world, living only in the present, from the giddy confidence earned at the end of UC (I realize they're not the same character, but the progression of thoughts is there). If the character in the song is giddily hedonistic, why shouldn't the music be? Similarly, Boots, is about another character seeing the world collapse into warfare around his eyes, but keeping it only in his peripheral vision. It fits the music perfectly, especially with the under-the-surface Middle Eastern rhythms of the song. And then there's the ironic quasi-attack on egoism... the very self-centered egoism that is embraced by the two songs before it, Bono is embracing in a very tongue-in-cheek way, suggesting that all is not well in hedonism-world. Again, the hard edge of the music fits this perfectly. And then the world collapses into chaos with the renewed chaotic surrealism of Fez.
What doesn't fit?
