A sweet song by Megadeth, written by Dave Mustaine when he was still in Metallica, they took it and changed it to four horseman. Mustaine responded by making it really fuckin' fast and putting it on Megadeth's debut album killing is my business, which is also amazing. It is about working in a garage and fucking a female customer.
