those are not subgenre tags. Those are just descriptions people used. Are Venom and Motorhead speed metal bands when that term was used to describe their sound by numerous people back in the days? you said it was used in late 90's. no one used metalcore in the 90's. Some dude referred to their sound as metalcore in the 2000's, that doesnt equate to them "inventing" the subgenre(like you said), all that means is that they invented the term. Tera did, im responding to both of you again, that was not directly in response to you, just saying you guys can use it to describe those bands y'all mentioned. And i find the whole "Proto" anything stuff to be nonsense. People need to stop using it as if they're some kind of subgnere of their own because we can literally start applying to dozens of bands from different sounds when it comes to whatever genre it is people are trying to apply said "proto-whatever" label to. its pretty ridiculous if you ask me.
