The depth and breadth of all the sub-genres of metal is really pretty shocking, even for people that have listened to it all their lives. I have a slightly loose definition of metal, so in my mind I can go from Blackened Thrash/Death from someone like Skeletonwitch (an all time personal favorite), to whatever the hell 3 Inches of Blood is (all I know is it's awesome), to viking themed Death Metal, to all acoustic stuff from Eluveitie, all the way to a cello trio like Apocalyptica or maybe even Break of Reality (less so) and still be "in the genre" so far as I'm concerned. Its amazing.
