Who knew so many songs drove people nuts?
Personally, mine is "Bodies" by Drowning Pool. Radio stations were playing the heck out of that right up until the early hours of September 11 2001. Then suddenly a song with a chorus of "let the bodies hit the floor...." didn't seem appropriate. I tend to agree, and I'll never be able to disassociate the event and the song.
Good band, good song, horrible luck.
