I’m not sure what kind of music scene there is where you ware, and I currently don’t KNOW where you are xD, I also don’t really enjoy lables, but, I undertand why people use them. It makes language easier.
Anyways,
-concerts (at clubs if you’re under 18 a lot of the shows are usually all ages, and depending on the band there would be TONS there. Also, usually inclubs, but also depending on the band, you pay at the door and it’s really cheap. I just went to a show that was $7 at the door.)
-Parks in the midst of downtown (if you live in a city)
I’m going by my city, by the way, but if you live in a city there’s a good chance some of these apply.
-Dark fashion stores
-Stages, basically anywhere where there’s music.
Depending on the style of music, there could be different amounts of people there.
If and when you do find someone you like though, DON’T BE AFRAID TO TALK TO THEM.

Best Regards. :3
