Can it be done? Is it done already? Let's say I complete Crysis1/2/3 or Mass Effect 2/3 or Star Craft 2 or anything and I'm into replaying these games again and again..Wouldn't it be nice to mute the in game music and just play your own Spotify playlist or media player whilst playing? Just mute the music in game and rock out? Can that be done? If it can't legally yet then it should be!
