Frogman, jazz can not be properly defined; if something can not be properly defined, how can it be objective?
Many jazzmen have objected to the word "Jazz". As far as I am concerned, it only defines the music up until the 70's. Some want to argue whether or not Pat Metheney is a jazz musician, I don't because I like much of his music whatever you call it.

I like this music regardless what you call it. I find "stereotypical" jazz boring.
No I'm not defining jazz, I'm defining me, as you should define you.
Enjoy the music.
