Fighting Volume

In my campaign there is an entire map where I want the music to be ALOT louder than the fighting so that you can actually hear it. How can you make the volume of the fighting go down?

Help appreciated.

You can try putting the volume of the music up past 100%, to 150% or such, don't know if this is possible though...
If you don't know how to tell me, i'l explain...

Also, you could pick all sounds and turn down the volume, dunno how to do this though...
