i turn my music off ingame.in real war you dont have music blaring in the background so why have it in game? sure some may like but it detracts from realism and without it you can hear a pin drop when an enemy is near.but as you said just an opinion and others may think different.

and before some of you young whipper snappers start nameing when we used it as phsychological advantage it doesnt happen everytime and they just dont issue someone in a fire team a boom box to carry around to play music while your in regular gunfights...kk
