Or you could put actual
well known metalcore bands on the list.
The problem here is two fold:
1. You are trying to sell a survivor genre that is as about as popular as nu metal.
2. Half these bands aren't really signature metalcore bands, they're obscure metallic hardcore bands from the 90's that no one gives an F about. How could you leave off the following???
Avenged Sevenfold - Nightmare number 1 US charts
Bullet for my Valentine number 3 US, charts,
Killswitch Engage's last two albums broke the US 7
Black Veil Brides US 7
August Burns Red number 9 US,
Bring Me the Horizon, number 11 US, number 3 UK, and number 1, Australia.) ect, ect.
Its almost as you yourself hate the genre so much that your trying to cherry pick around the reality that is metalcore, but batsy, there is no escape from the horror above.
That is metalcore!
