Why is in game audio and music mixed together.

This obviously on xbox 360 needs to be changed. We were able to reduce music to 0% in the other cods.
We want a patch update to be able to do this. If this can't be done, this is one of the worst cods i have ever gotten. And this will drive me away from playing this game in the future. I'm telling you now, it's the worst idea ever. I dont' want music playing in game, i want too hear my teams and enemies footsteps whether or not the match has just started or is about to end. IT makes NO SENSE that this game doesn't have this function. if i want to hear music, it's going to be what i want to hear, not cause you purposely keep us listening to the same theme music. Give us the option to turn it off. When are the dedicated servers coming?
