This is not a quality argument. Individualism is not inherent to each individual.
Jazz expresses spontaneity, huh? You have low fucking standards for your art. Jazz denies structure because it's incompetent at it, but structure is what communicates something unique to each piece.
Metal has it, classical has it, and some electronic music has it. I prefer that to every piece being a variation on the same old never-ending jam.
To the idiot who said that jazz is about feeling: what a pretentious retard you are. All music is about feeling, and has feeling. You're just being a pretentious fucktard so you can feel how different you are. I have news for you: stupidity and self-delusion aren't unique or different. You failed.
Going back this this. A lot of jazz has very simple structures, simple to the level of blues and verse chorus styled rock songs. This makes up the majority of the most popular forms of jazz. This is esspeically true about stage bands who perform swing and many other kinds of more popular big band jazz. But it also has much more complex structures. This becomes more true as to the less popular the jazz becomes and the smaller the bands become.
There is some Jazz which fits your description of it (if loosely so) such as bebop, but bebop was an style of jazz that went against many jazz standards. So you description of jazz goes against many jazz standards that are prevalent throughout jazz.
But going back to the very first post I find very little jazz interesting and none of the music you posted held my attention for long. Musically jazz is interesting and can be a useful tool if studied to enhance your own compositions but as a genre in itself I see most of it as the same as Britney spears. There is only a small amount of advante garde jazz that I can tolerate, and thats tolerate not enjoy.
I just find almost all jazz to be the same old everything is going to be alright mentality.
