Many people attribute the number 13 to all kinds of bad luck. Friday the 13th, Apollo 13, you name it. The number has often wrought disaster for some. To me it's a good luck number. However that doesn't mean I can't make people dread it more. This song is the paranoia of bad luck personified. Lot's of tension, lot's of edge, with just a slight calm before it begins again and even the calm is scary.
