Dance music, if my crystal ball is accurate, is destined to be socially subversive. It may be one of the few ways to really connect without sex. It is like entering a different world. That's why through history dances were often tied to religions as a form of prayer. The whole purpose is to fulfill the need our ancestors in prehistory knew well.
Dancing is fun in that there is a feeling of connection to the people one dances with.
You share a vibe. Look at all the primitive orgiastic rites. These were not about sex, but about getting the group spirit going. Western culture has lost this fundamental, magical way for persons to connect. When the whole tribe does it, no one is alienated.
