I sing to that shit in the shower every night so it's on my list as well.

Anything at all by Ill Nino, though their latest album is quickly cementing its place as my favorite of theirs with songs such as Against the Wall, Ritual, and Bleed Like You.

One Brain by Mobile Deathcamp
Rock & Roll Party Town, Whargoul, None but the Brave, and Nitro Burning Funny Bong by GWAR
