The point is that a dance sequence is planned. Its no product of meaningless random movement.
Perhaps a 'dance sequence' is planned, but that does not make all dancing planned - I don't plan when I dance, I try to give myself over to the music. Your statement might be true for a square dance, but not for a mosh pit.
No matterr what the painter's style he wants to achieve a certain impression. He doesn't just make a mess with the paint and suddenly art comes out.
Ever hear of Action Painting? Jackson Pollock and his contemporaries?
Jazzlover - you seem to argue a lot by generalization (as in, no such thing as rap music with 'harmony'). In these sorts of discussions I think it more interesting to look not at the 'average', but at the extremes, where the boundaries of 'art' are pushed.
That the best musicians all around the world agree that music comes from the spirit...
Do you have a source for this bold statement or is just your opinion?
Go ask profesional musicians in your town (when i say profesional musician they must have at least bs in music performance or education) if the purpose of what they do is to get laid. Find at least ten.
By your definition, Beethoven, Igor Stravinksy, Paul McCartney, and Miles Davis were/are not professional musicians...
Why must a professional musician have a bachelor's degree? A professional musician simply is one who gets paid to create music - I would guess that if you took an accounting of the great professional musicians, historically or presently, a minority of them would have advanced degrees in music.
Besides, how does a BS in music qualify someone to discuss the evolution of art? It's like arguing against old earth geology by telling me to ask ten preachers in my town what they think...
Regarding musicians and sex: are you asserting that "groupies" don't exist? That professional musicians are not more attractive to the opposite sex as a result of their musical skills?
Also, keep in mind that just because a scientist believes that music originated as a means to create social/mating connections does not mean that the scientist is not a musician or someone deeply moved by music.
The initial origins of music do not change the power of music to move the spirit.
