Bad Moon Rising, Creedence Clearwater Revival. "Bad moon" is often mistaken with "bathroom" by idiots.
All Along the Watchtower, written by Bob Dylan, but played much better by Jimi Hendrix. Also the title and inspiration of a post I did about Big East defections about 15 months ago.
99 Luftballoons by Nena. Idiots think it's simply about balloons, but it's really about how the release of said balloons accidentally triggers a nuclear war between the Soviet Bloc and the West.
Gimme Shelter by the Rolling Stones. Interesting story, Merry Clayton, the woman in the song had a miscarriage very soon after recording this song apparently from the stress that recording put on her.
Armageddon It by Def Leppard. In this case the reference to the apocalypse is really just a play on words, but the word armageddon is in the song! Also, Def Leppard is really cheesy and I am including them for precisely that reason.
The Future by Leonard Cohen. You may recognize this song from Natural Born Killers which is pretty relevant today given the way it portrays sensationalist tabloid journalism, and America's thirst for coverage of violent tragedies on the news. But yeah, the song is awesome in its style and its vulgarity.
London Calling by The Clash. I thought it was pretty ironic how much this song was used this summer for the Olympics, because it's really about London being destroyed. Using it to promote an event that values peace above everything is a pretty post-structuralist application of the song. This is also included because lead singer Joe Strummer died ten years ago tomorrow. RIP
