There are way to many genres in music if you ask me. The only ones I really see a need for are the classic ones like country, folk, rock, metal, jazz, blues, hiphop/rap.
I mean Heavy metal, speed metal, death metal I get that, and I've said this before, but I just think a lot of these newer genres are either too niche or vague ..lincluding stuff like progressive rock/metal...but more so stuff like horrorcore, hardcore, new age
There's just too many in general.
