Does music *EVOKE/PRODUCE* emotion, or simply make you realize what you already are feeling?

It can do both. take football players or any athlete who listens to music its to keep a certain mind set, most likely a power lifter wouldn't listen to Celine deon to get pumped up. sad music or love music will always tug at your heart because it makes you think of sentimental things, a rough relationship, a argument you get into or make you feel even more for someone. aggressive music can be bad to listen to when angry because its meant to bring out anger or a adrenaline like feel. so i would say both. evoke, and produce.
