Quite the opposite! I was so into the music I couldn't concentrate on the game! I had to tutn it off because it was WAY too good! Man...I can't say that with a straight face...
I so often find myself muting the music on games, it's not even funny. I've actually created some playlists to listen to when playing certain games, my favorite being a great metal one for the Diablo II Marathons I used to play.
Madden doesn't give you the option of turning off their music and creating your own playlist from the HDD? That's what I did with MLB the show and it made a world of difference. Their setlist was mostly terrible. It's at least good they'll include some real music with the game this time around.
It's built into the 360. Any game's music can be replaced for a custom playlist. It's one of my favorite features. It made Oblivion a whole new game.
