Sorry, was away for a month. I got that much Metallica on my station by thumbing down every song except Metallica songs. Eventually if the Metallica station is the only station it will say ''more info is needed to play new songs'' and will only play songs you have thumbed up. Which should be only Metallica. The Metallica station needs to be your only station, I just made a different account for when i'm in the Metallica mood.
...examples of what most metalcore sounds like. The second style is deathcore, which is a hybridization between metalcore and death metal. The main difference is that the riffage between your breakdowns is going to be quite a bit more technical, and the sound as a whole will be more "brutal". Vocals are going to be closer to death metal than thrash or post-hardcore. Good examples of deathcore are The Agonist and As Blood Runs Black. And there you have it. Hope it helps!
re metalcore: There are essentially two different style that are similar that both get labelled as metalcore. The first is metalcore, which is basically a hybridization of post-hardcore and thrash metal. It's extremely heavy on breakdowns, and has a little bit of riffage to fill between your breakdowns. Vocals are usually either similar to post-hardcore screams or thrash screams/growls, and some bands use clean vocals as well. As I Lay Dying and the Austrian Death Machine are fairly good...
