Radiohead- 2+2=5

1. Lyrically, I think the song is saying that some things are never going to be perfect, and the people who believe that a Utopia is possible are unrealistic.
2. The music starts slow, then gets faster. The difference in pace of the music shows the unpredictableness of life sometimes, and the irregularity that it can bring. It reinforces the idea that a Utopia is not possible.
3. I think this relates to 1984 because in that book, a dystopia is occuring, and when people in the book think it is a Utopia, they are mistaken, as stated by the lyrics of the song.
