I can stand literally anything but metal. Try me.
I'm curious where the line is drawn between metal and anything else. The speed, types of vocals, relative "heaviness", the tone of the guitars? Have you ever accidentally disliked hard rock or hardcore punk, thinking it was metal?
I haven't yet found a group that I thought wasn't too raucous and had vocals I liked in the genre. I've disliked a lot of hard rock, too, but it's not all across the board. Granted, I stopped trying after about two dozen, so...
To be fair, I liked symphonic metal when I was 15-16.
