The list author says: "Metalcore/Hardcore, both genres intertwine with one another. This is mostly because most Metalcore bands are also considered Hardcore bands, yet sometimes people do not like to refer to Hardcore bands as Metalcore bands. The best thing to do is simply use the term Metalcore. Metalcore is a form of metal that utilizes blast beats and breakdowns. The vocals usually resemble a harsh "yell" and many bands also utilize clean vocals. This list contains (in my opinion) some of the best Metalcore bands out right now. Since Metalcore is gaining mainstream popularity, many of these bands are probably all known. So, I recommend checking out the bands that you haven't heard anything by in this list."
