This is nice!
A funny thing happened when I opened this window. As soon as the song started playing the background changed to Saurons Eye from LOTR. That's when I knew this song was meant for an evil overlord. It'd work great on a flash game as the bosses theme. The only reason I rated 9 was that I've heard something very similar before.
Have you really heard it before, honestly i got it from no where. I started messing with my guitar and i did something that sounded cool and bam, i made this haha. But thanks, I think it does deserve to be a boss theme XD
