Don't mean to offend, but 80's metal sucks. Maybe because I play guitar and you always learn some 80's stuff first(because it is simple and easy). I think metal should be EXTREME and fast. If I had to pick 3 I would say BRING ME THE HORIZON, AS BLOOD RUNS BLACK, UNDEROATH(the old underoath, Act of Depression, and Cries of the Past) I would say A Love so Pure from underoath is my favorite song, its pretty hardcore christian, great lyrics and very spiritual if you're into that, but you wouldn't think so if you heard it for the first time, check it out on youtube. Jesus Christ, I love you!
