Is there such as thing as "perfect" healing music?

When I go out to speak to large groups of people, someone eventually asks me what the "perfect" healing music is. Well, unfortunately, there is no one such piece of music. When choosing healing music, you want to consider: The purpose for the music: calming, energizing, comforting? The type of music the person normally likes: classical, jazz, Big Band, oldies The situation and place the music will have: home, hospital room, car? Those are just a few of the many parameters to consider. I include here an example of a piece of music I have always loved and still find very calming, soothing, and comforting. Tell me what you think!
