A devious trap

Music is wonderful.

I managed to invent a trap today, for one of my projects I'm writing. Now when I have a mp3 player I can listen to music on the bus downtown, or when I'm waiting for a friend to meet me. As I was listening, absentmindedly, I suddenly heard a few words of the lyrics, and at once I knew it was an arcane and interesting thing I had to write about. Where do you get your ideas? Heavy metal lyrics, of course!
