I'm only familiar with metal genres, but it doesn't look bad. It's way better than Wikipedia, for example. There are no "gimmick" genres like aliencore, and every style mentioned is distinctive, historically important and accepted by me and the people I interact with. The only thing that surprised me is that first wave of black metal is called "extreme metal" here.

If anything, it's not detailed enough. For a long time I was listening almost exclusively to technical death metal, while for example I don't line brutal death metal at all. These subgenres of death metal (and band self-identification) are very different, and yet here they are all lumped into just "death metal", as far as I can see.

I'm not sure about the quality of other sections.
