Okay, here's a few: Portal: Still Alive, Halo: Mjolnir Mix, A Perect Circle: Passive, Breaking Benjamin: Blow Me Away, Metallica: All Nightmare Long, Disturbed: Land of Confusion, System of a Down: Toxicity, Korn: Freak on a Leash, 115(Call Of Duty: Black Ops Zombies theme), Linkin Park: Numb and In the End, Green Day: American Idiot and Boulivard of Broken Dreams. And yes, that's just a few.
How can you even ask a question like that? There is no real answers because everyone has different opinions about music. Now there are very many good song but the best, that is only a song chosen by ourselves. one good example is me, I love the song Welcome to sludge city by annotations of an autopsy. Many say that music is garbage but i like it.
