Query: Professional Badass's Soundtrack

Oh man, this album kicks some major ass. If I'm not wearing headphones, there is no way I can't headbang while this album is blasting. And I've tried with headphones, they just come flying off and I can't hear the song anymore, which sucks, which is why I don't do it. In other words, this album makes you want to buy a strap for your headphones, or if you don't care about waking the neighbors, makes you buy a full Marshall stack, hook your CD player to it, turn all knobs to Max, and play the loudest metal you've ever heard outside of a concert. Like I mentioned above, if my job was to just walk around being a badass, this album would be my soundtrack. Some death metal comes across as ridiculous, with the unusual vocals and all, but people know not to mess with Lamb of God. I mean they're called LAMB OF GOD. Probably the best band name ever. And they make a sweet ass album too.
