To me, Music As a Weapon means that people often use their favorite music to change their mood. I know from experience the music can bring you up when you're down, make you strong when you feel weak, and let you just let go and relax. Music is aslo an amazing tool. Advertisements use it to influence a certain group of people to consume certain goods, and supermarkets even use it to get you in a better mood. Music is a huge part of life, whether you know it or not.
