Metallica ---"Motorbreath", "Fuel", "The Mechanix (demo)" (last one has a double-meaning, not completely about cars but you get it)
Sammy Hagar ----"I Can't Drive 55"
White Zombie--- "Black Sunshine" (lyrics don't always make sense, but parts still have to do with a car. and the video includes a kick ass mustang)
yes I know that not all of this is purely metal. don't fuss about it XD I know I probably have other ones I love, these are just the ones I can think of right now.
what are some songs you can name that you love?
