"Once when asked what Trans-Siberian Orchestra was about, Paul O'Neill
replied, "It's about creating great art. When asked to define what great art
was, Paul said, "The purpose of art is to create an emotional response in the
person that is exposed to that art. And there are three categories of art;
bad art, good art and great art. Bad art will elicit no emotional response in
the person that is exposed to it, i.e.; a song you hear in an elevator and it
does nothing to you, a picture on a wall that gives you the same emotional
response as if the wall had been blank, a movie that chews up time. Good
art will make you feel an emotion that you have felt before; you see a
picture of a forest and you remember the last time you went fishing with
your dad, you hear a song about love and you remember the last time you
were in love. Great art will make you feel an emotion you have never felt
before; seeing the pieta, the world famous sculpture by Michelangelo, can
cause someone to feel the pain of losing a child even if they've never had
one. And when you're trying for these emotions the easiest one to trigger is
anger. Anyone can do it. Go into the street, throw a rock at someone, you
will make them angry. The emotions of love, empathy and laughter are
much harder to trigger, but since they operate on a deeper level, they bring
a much greater reward."

I think this is a much better description. Even though it totally defeats my earlier arguments.
