I wasn't even looking for it and if you would have asked I would have said I wasn't in the mood for trucker music. But after a few random clicks I ended up on Red Simpson's "(Hello) I'm a Truck". It hit the spot. The Bakersfield sound of it, his rap in the middle of it, and that it's a truck singing about it's owner. Good stuff too, the shame of being passed by a "Volkswagen bus full of hippies".
