While someone can claim title to a song, no one can own a genre of music. Although "Jazz" originated here, the many "fusions" with music from around the world have made it much better. As far as the word "Jazz" is concerned; on one hand it's too confining, and on the other it's too amorphous to have a definitive definition; therefore, I would concede any argument in regard to the word "Jazz". For those who want to claim exclusivity to the word "Jazz", I say "let them have it". The music, however; is what we hear and feel around the world.. Let's call it "The free peoples music".
As someone once stated, "Free your mind, and the rest of your body parts will follow".
