Why Does All Jazz Sound The Same?

Just my opinion , but I don't think it all sounds the same. What I consider to be traditional Jazz sounds nothing like what I consider to be modern Jazz. Neither sound like fusion. Your definition of modern, traditional, or fusion will probably influence your opinion.

Good question. Why does all food taste the same? Answer that and you've found the answer to the question about jazz.

So does all rock, classical, etc to you?  Perhaps it's the style of Jazz your listening to?

If all I heard was squeaks honks bangs and tinkles I’d love it as much as you do.
