Well when it comes to such boredom-killing games as KnD then it makes no difference to me whether there is music, some movie playing in a background or playing on Android while comuting, but when playing for instance Counter-Strike or League of Legends I highly prefer full silence, door shut, sunlight covered by shutters and my headphones on. But I play (or rather used to play) both of those games on quite a profi level, so there was more 'I NEED TO WIN' than 'GIRLS JUST WANT TO HAVE FUN'
