I myself am not a CoD player, but I like to enjoy the music for (almost) every branch and I do so with Advanced Warfare. OK, it has 2-3 ears needed until I recognized the brilliance of it. Audio Machine put this off to a very strong showing, whose songs are mainly characterized by aggressive drums, accompanied by other instruments and "effects", while the good Harry Gregson-Williams provides classical music and melody.
There is no other Black Ops 2 (because these plays so well in the future) but fascinated by its own charm and sound. The total length is approximately 1:17:00.
