Add the genre tag "Loud Kei"- a subgenre of visual kei that is focused more so on deathcore and similar heavy genres, such as metalcore. Visual Kei as a genre goes from everything from soft kei (soft rock) to loud kei (deathcore) and Showa kayou kei (specifically loud kei with specific imagery and visuals that are a part of the genre) and is too broad a range to genre tag specifically. Whilst "visual kei + deathcore" do typically work, loud kei also still has specific parts of v-kei genre typing making it ever so slightly different in some sounds and tone and is it's own specific area

It's the same as only having "metal" as a genre on the site and removing all other forms of genre tag for it.
