Then I suppose my only choice is to interpret your words to the best of my ability.
Riot Grrrl is a genre that is centered around feminist themes. So anything from this "category" or genre from Japan would be fine.
But on the other hand, I'm more interested in themes than a "category" or genre itself. Riot Grrrl is not the only genre of music with feminism. It could be grindcore, emocore, death metal, visual kei, poprock, darkwave, anything, any "category". Any genre is fine, I'm just looking for feminist themes.
I hope that cleared up some stuff about categories.
