Doug?
Hey, that was just like the theme to "Doug" in the beginning; gosh has it been forever since I've seen that awesome show. Anyway, I'm not really familiar with Halo music, so it's a bit hard to judge. I can still appreciate this for having a pretty interesting tune to listen to. As stated before, the repetitive humming works really well for a song at all. I couldn't even tell it was grunting, as it really only took that at the end and for the most part it seemed like humming. Not the best, but quite impressive.
