So, I really pretty much can't stand Rihanna. Except for Disturbia. That song kicks some major butt. Anyway, Black Nail Cabaret is this amazing... darkwave? dark electro? Eh, duet which creates goth-approved music of an electronic persuasion. And they covered Umbrella back in, like, '08. And if you aren't floored by the awesome, I don't wanna know you.
