Teen pop and pretentious indie.
Wait...this was about evil music, not bad music. Never mind.
In all seriousness though, the only stuff I might give that label to would be some of those cases of black metal, what with the church burnings and violence. But I make a distinction between the genre itself (which is, as all genres based on musical composition are, neutral) and the actions/beliefs of some that perform in said genre. Of course, I don't really care for extreme metal - of any stripe - save for isolated tracks here and there. Has less to do with the lyrical content and more to do with the aural punishment involved. I draw the line at some Turmion Kätilöt and melodic death, pretty much.
