From my personal experience, music is very powerful. It can make me sad, happy, feel nothing, and all the emotions there are. It can alter my moods. When I listen to music when I am sad I feel consoled. When I am depressed, I listen to it to feel encouraged. When I am low and don't want to move, I listen to it to feel motivated. It helps me a lot that's why for me it is so magical, which makes me consider it therapeutic.
