Aristotle, let me know when you want to stop playing childish word games and want to discuss something of substance.

This is all melodic stuff, of course, not harmonic.

The above is a description of blue notes, as they appear in practice, using classical interval terminology. It's sufficient as such - IMO - but is hardly a "theory".

So I think prediction is not the object. What then?
The only aesthetic theory I can think of is Edmund Burke's, who said the sublime always carries an element of terror, and that's why people like mountains. The predicition: if they don't feel terror, they won't perceive it as sublime, so you have to make mountains scary looking when you do a painting of mountains, if sublime is what you're aiming for. How valuable is this theory when painting? Very little, I would guess, but I've never tried it out.

Of course, the "theory" may be entirely artificial, but is judged on it's ability to describe what sounds good. As to your need for predictive value, we could say that if the theory allows music that is aesthetically displeasing (to said culture) then our confidence is weakened. In that case, the theory needs to be made more specific - which is what theorists do.
Of course, since the mind is a black box and it is programmed by complex cultural interaction, any theory is going to be an abstraction of an invisible process - it can never be a concrete rule without subjectivity and even arbitrariness. Therefore, in many cases there may be more than one explanation for a musical "phenomenon" and this is completely acceptable.
But I think that they danger is thinking that the word "theory" means the same thing in science and art. In science, the theory is attempting to describe an an objective phenomenon of the physical world. In art, a theory is trying to describe the function of a completely artificial and essentially imaginary construct, and judging it on aesthetic values that are constantly in flux and are nearly completely subjective.
For a music theory to be useful, I don't think that it needs to explain how something works on a neuron level. I think that it just needs to select a certain phenomenon, label it, and attempt to create a theoretical model that can explain what is happening. Ideally, it should suggest other things that sound good and not suggest things that don't.
That's how I might sum up my thoughts on that anyway, unless someone has a better description.

I like the story of Beethoven and his tutor. Beethoven had put some parallel 5ths in one of his exercises, to his tutor's dismay:
"But Ludwig, parallel 5ths are not allowed!"
"Well, I allow them."

Wow this is a seriously old thread - but an interesting one...
There are definitely blue notes in other styles - Flamenco is another example.
Personally, I think there is no such thing as jazz harmony. Harmony is harmony - understanding classical harmony will help you get inside standards and earlier jazz forms, and getting into Debussy, Hindemith, Bartok and Ravel will give you an insight into most modern jazz harmony. But they need to sell some something because they sure as hell can't teach cats to swing haha.
At least that's the perspective of most of the older generation players I've had contact with, I can see the point.
The big divergence with classical harmony is the blue note, as mentioned in the OP. But that is primarily a melodic embellishment that can be used to enrich diatonic harmony - V7#9, V7#5 and so on.
