A local radio station recently did a whole block on "murder" songs...songs about violence, good and bad, quite literally, run all the way through the spoken traditions. I've done a lot of blues songs on the podcast, dating from the beginning of recordings, that had the same subject matter as "Pumped Up Kicks."
It is our nature, perhaps, to glorify violence because we monkeys are so darn good at it.
After all. I shot the sheriff, but I did not shoot the deputy...
