Race Music

The other night I was walking around listening to the radio on my walkman (last one on earth) when I happened upon a station that was playing that whack-shit, crazy-ass circus carousel music I always hear in the bodegas on the southside near my house, and I began to wonder how come this music makes me sprint like a wolverine after a Starbucks visit, yet it makes the dude at the counter of the bodega fall asleep while taking 10 minutes to put my turkey sandwich in a bag? What the fuck?
