i nvr thought if it like that. thanx man you just completly changed my perspective on music in games :yes:
Another example is if you are using a headset (Turtle Beach for instance) the sound quality of your game almost doubles, you can hear things like footsteps or even people reloading and tell what direction they're coming from. It can really help with Battlefield Awareness, the leading cause to most deaths.
Now imagine trying that with music drowning those small details out, makes it real hard to know whats up.
