What's your #1 driving song?

I'm driving overnight to Iowa Thursday night. I'll pick up the wife from work at 2300 and we're gone. She will crash immediately. I'm looking for the best driving tunes for the 11-12 hour ride.

I'll probably just build a playlist from this thread, in order - hopefully there's stuff I haven't thought off or even heard of.

I'm into almost anything from Rush to Slayer, Pink Floyd to Beastie Boys, so really nothing is out of bounds (except pussy boy band shit and whining girl songs).

I'm starting with:
Rush: Red Barchetta.
