Is there pop with harsh vocals? Or growls, or whatever. Sang entirely that way, not a scream here or there in a couple of songs.
Can be any kind of pop. Synthpop, electropop, j, american etc

Does this fit what you're looking for? Semargl's new stuff? This is actually from an album called Satanic Pop Metal.

That's the closest thing I can think of.

That bitch fest in the band genres thread reminded me of Solution .45, not exactly what you're looking for but it may be one of the closest things you'll find.
