Great topic! I usually listen to:

Anything in the genre of Heavy Metal, Hard Rock, Hardcore Punk, Heavy Blues...

Songs? I listen to hundreds of bands and musicians, I can't really be as specific to name my top 10 whilst in the car.

How about my top 10 bands I listen to the most?

Pantera
Slayer
Anthrax
Megadeth
Venom
Napalm Death
Bathory
KISS
Immortal
Mayhem

And a whole load more. Constantly brake the speed limit!
