The "grindcore" tag is a remnant of the days when every fucking scene kid somehow thought deathcore and grindcore were the same fucking thing. Don't ask me why, that's just how they used to think back then. Deathcore kids aren't any less annoying these days as they've evolved into goddamn try hards who think anyone gives a fuck how "brutal" they think their music is.
@HeyJohnWhats: Nah, I'm pretty sure the band is still called Suicide Silence, and everyone who wrote the music is still there. It's not like the band was called The Mitch Lucker Band, or Mitch Lucker and the Suicide Silences, Mitch Lucker and the Suicide Silence Band etc
