Music can help and hurt

What good does music do? Can music hurt or make someone feel better? Well I think that music can help you focus more. I listen to music every single day. It helps me relax and it helps me go to sleep. Music also has a message for everyone. Like a song called "Beautiful" by Christina Aguilera. Her song lets people know that they are beautiful inside and outside. No matter what people say or do, you are beautiful. So my question is does music helps you or hurts you?
