You people suck horribly at classifying metal bands. Aside from the fact that there's probably a dozen more retarded subgenres to list, it doesn't matter and only newby was anywhere near right.
I only elaborated on the ones iago mentioned. I didn't feel like mentioning goregrind, crust, viking, epic, atmospheric, doom, progressive, symphonic, folk, or any of that other crap that I do not listen to.
Well, I occasionally dabble in goregrind.
