Feel Good Music with Joey Blake and Bobby McFerrin

I watched this video yesterday several times. It is so fun, bright and uplifting. It made me feel good all over.

Is not the fact that music makes you feel good enough of a reason to say it heals? What is healing? Is it a "curing" of symptoms or is a shift in consciousness? If you go from feeling poorly- physically, mentally, or emotionally- to feeling light, happy, positive- does it matter whether you took an aspirin, had surgery or listened to a fabulous piece of music?
