Bang Your Head
Hi! Welcome back. Apparently, there aren't enough fuckers dying of plague so you're just in time to help us all out!
Well anyway, since you went the free route, the songs are easier to make into flashes.
I also notice the riffs you use are very trademark, in a sense. You could string several songs from your catalog into a complete bad-ass metal soundtrack for a game (hence my BBQBeefburgerman concept and, wouldn't you know it, that guy made another flash to prove who rules the portal and shit!).
Pretty soon, a bunch of metalheads will be pumping out tracks and forming albums, inspired by your attempt. And they'll probably pale in comparison to this one track alone.
