The Different Metal Genres

In this article I try the impossible task of categorizing the sub genres of metal. It's "impossible" because definitions are vague, and most bands cross between multiple genres, which makes it tough to categorize a band as one particular thing. But for the fun of it, here's my stab at the impossible task. If you disagree with anything I write below, feel free to email me, but do note that on this topic, I believe no perfect consensus can be reached.

NOTE: This is not a complete list of ALL metal genres, for example, no mention of Black Metal or Viking Metal, this is just the metal genres you're likely to see reviewed on this website.

Heavy Metal
Death Metal
Hardcore Punk
