Music is like art. It holds tremendous power with the ability to touch another's soul. And like any other form of tremendous power, it must be used responsibly lest it become a tool for great evil. For music has the power to both destroy and heal. They do change people and cause the world to change in turn. The question is for better or for worse? That entirely depends on the person behind the scenes. There's a quote that I like: "Power doesn't corrupt people, people corrupt power." - William Gaddis
