Fix Music in the Campaign

After playing through the campaign a couple of times I don’t really notice the music much in most of the levels because it is drowned out by the gun and vehicle action going on. However on the last mission the volume of the music gets louder and really makes it a better experience does any one else think this or have this problem because its really annoying me. Also having a little listen of the soundtrack there seems to be some good track on there but I haven’t really noticed most of them when playing the campaign.
