Metal/Emo Karaoke?

I absolutely love doing Karaoke at bars and stuff, and my favorite music is metal, but I don't want to be THAT guy singing angsty/depressing songs while everyone's trying to have a good time lol. I usually end up just choosing something kinda crowd pleasing, but I'd love it if there was a place where everyone was there for the heavier stuff. Anyone know of any places that might do something like this? Even if it's just a once in a while kind of thing.
