Yes
- Music isn't art, or at least it's wrong to appreciate it as such.
Music is entertainment and emotions.
- Jazz ought to be revivalist, not innovative.
Things like free-jazz is not innovative. It is shitty musicians thinking that if they play "out" enough, they might get to the point that people feel they are geniuses.
Music is meant to be good to the ears.
Coltrane played 'out' a lot, he surly wasn't a shitty musician. Cecil Taylor has more technique on the piano than most anyone. Sam Rivers harmonically is out of this world. Ornette Coleman's sense of time? Hamid Drake on drums? Pharoah Sanders? Don Cherry? Marion Brown? Eric Dolphy? Anthony Braxton?
Just because you don't like how it sounds doesn't mean these are talentless fools -- they've studied their history. They surely think about their art complexly and take it extremely seriously.
If that's the case, then I'd say that in WWF vs music, WWF wins every time!
I'm going to go out on a limb and guess that you think all post-renaissance painting is shit, too.
Think about the culinary arts. It too is an art, but with even more restrictions on what can be done than music. "Experimental Chefs" can't just start dabbling in putting sawdust and latex paint in their dishes and still expect it to be eaten.
That being said, experimental musicians have the right to push the envelope and discover what the boundaries of taste are. Sometimes they'll fail, and sometimes they'll discover something interesting, but experimentation alone doesn't cause it to be good or bad.
A more substantive reply: I question the entire underlying premise you have -- that entertainment or emotion are what makes art, art. Something can be entirely distasteful and still art. (Thought experiment: imagine a sonata so deeply heartbreaking that nobody can bear to listen to it more than once. One can't "develop a taste" for it, can they? But it's almost certainly art by most definitions.)
In any case, I don't think John Cage is having any trouble finding listeners, despite your opinion: http://www.johncage.info/index6.html
If all you have been exposed to is 3 (four-five-one four-five-one) chord pop rock, no of course you won't appreciate Cage. In music, like cooking, you have to develop a palate for such things.
If all you've had all your life is french fries and ketchup, you probably won't like a lot of food that others will appreciate...
