We need a background music volume slider. With the recent addition of the usb music player on ps4 I have realized that the destiny BGM is too loud and needs to go away. Please implement this so that I can listen to my music. I realize that people may "abuse" this in Pvp or whatever to hear footsteps or whatever. It's not abuse if you can do the exact same thing by the way. If they have a better headset they can hear more anyway so don't cry about Pvp sound or whatever. WE NEED THIS ASAP
