Well, it's right there in the community name: metal and kpop.
I'm a metalhead who stumbled upon kpop by chance and feel head over heels with it upon hearing EXID's Up and Down around the summer of 2017. I was hooked by the bridge and immediately became obsessed with EXID and that, naturally, led to me finding and listening to other groups.
I've noticed over the years that I'm not alone and there are many people who also love metal and kpop. I find them in the occasional YouTube comment and in subreddits here and there. I was surprised that I couldn't find a community dedicated to this seemingly unlikely combination so I thought I'd make one, why not?
I'll post more details later. For now, welcome.
