Haha yeah i always feel chill listening to opera when i play. It's calming and I think it cancels out the killing people. If i ever commit armed robbery, im listening to Nessun Dorma!
Downpour isn't bad at all. Some people like more maps than others, but you wouldn't have a favorite if you didn't have a least favorite. It's easy to take out the mg's if you know they are there. I do like me some chinatown.
My CoD playlist has Franco Corelli, Andrea Bocelli, Good Old War, Winds of Plague, Earth Wind and Fire, The Mars Volta, Circa Survive, Mana, Neon Trees, The Appleseed Cast, The Sound of Animals Fighting and very similar artists. What you got?
