Recommend me some good heavy metal bands?

Those 3 newer bands you named suck ballz. Start with the band "In Flames" , their album "Colony". Then go to other In Flames stuff, Children of Bodom - Follow the Reaper, August Burns Red - Thrill Seeker, eventually go to Cradle of Filth - Damnation and a Day, Trivium - Ascendency, and Dimmu Borgir - Puritanical Euphoric Misanthropia / Enthrone Darkness Triumphant, then Nile - Amongst the Catacombs of the Nephren-Ka / In Their Darkened Shrines, Anaal Nathrakh - Total F**king Necro / The Codex Necro / Eschaton, Emperor - Prometheus: The Discipline of Fire and Demise.
