Couldn't agree more.and metalheads hate hardcore punk. Might be just as heavy(if not heavier) but in detail, they're very different. I'm listening to more songs from Refused now, and if anything, their riffs feels like a good representation of Chrome Rock imo. They're not generic hardcore and has prevalent melodic vocals over screams that aren't randomly thrown around so i wouldn't call it screamo.
The problem is that in the trailer, we might have just gotten the taste of the ending of the song where it gets chaotic. We haven't even heard half the song yet, much yet the start of it. It might even sound like the previous ver at the start and builds up chaos towards the end.
If you don't have an ear for this type of music, it probably would sound the same. However, if Chippin' In would be played at a metal concert, the band playing it would be boo'd off the stage, cause it sure isn't metal.Still sounds like metal to me.
