What the fuck it "metalcore "?
Please give examples of bands who use this style and then I's might be able to answer your question.

Haven't heard of any of the bands (well, maybe Hatebreed, but I's heard any of their songs).
Anymore examples or should I's just saves time and says: "Yes. It is as evil as nu-metal"? Or is that evil or just plain bad? There is a ya'll knows.
