Music is a form of art which, like any other form, appeals to your senses. So, what makes music good or bad, superior or not, is one's opinion. I enjoy classical music as much as other genres. As we progress in time, new categories of music are created. In the 17th Century, there was only "classical" music. Today, we have a much wider choice. But I wouldn't go as far as to say that classical music is superior to any other kind. And if it is, it's in some people's mind and it could therefore be assimilated as a form of snobbism.
