mine has two. magic carpet ride (plays in austin powers when he goes back in time in his beetle vert) whenever i get a new car, i make a mix for it, and this is the first song on the mix, first song i played in him when i drove him off the lot.
and of course, OOOH CHAVO! chavo guerrero's entrance music
it's pretty embarrassing to crank up with the top down, but i don't care.
