Doom is awesomw.
This is one of my favorite Doom songs. And I think it's better than The Pit. The Pit is boring while this one, like you said, "maintains a creepy tone, while the heavy peddling keeps the badassness flowing through yo' veins". Thumbs up!
The Pit is much more better of a tune. This is still badass.
Please contact me if you would like to use this in a project. We can discuss the details.
