It really does fit the game perfectly. I couldn't imagine a song better for that ending. It's pretty cool that it got that kind of recognition.
Well, when I listen to that song Call Of Duty Ghosts inmediately crosses my mind, it is some kind of feeling that I ca not explain, it is just exciting, I really liked the song and it is way better when you listen to is while playing a deathmatch game.
Actually I do believe that the association with an artist like Eminem it's what brought the game so much notoriety in the first place, as the game seemed to be a real disappointment. I know some people who were never into CoD, yet they were huge Eminem fans, and bought the game only because of that music-video.
