2+2=5 by Radiohead
The English rock band Radiohead included 2+2=5 their sixth album, Hail to the thief, which was released in 2003. The song reached the #2 spot in Canada. The songs talk about things not necessarily being as they seem: January having April showers, two and two making a five, the term “hail to the thief” instead of “hail to the chief.”

The song is considered one of the best songs ever released by the band. Many Radiohead greatest hit compilations include the song. The song slowly builds up to a loud climax. In an interview with New York magazine, guitarist Ed O’Brien talked about the unusual time signature used in this song: “ One of the things that marks our band – that Thom and Jonny used to drive home all the time – is sounding different. You can do it through stuff like using unusual intervals on harmonies [in songs like “2 + 2 = 5”]. The trouble with a lot of rock music is that people are still doing their Beatles and their Crosby, Stills, Nash & Young harmonies. You can’t just keep making replications of those things .”
