Dunno, man
I have absolutely no idea. I would like better reliability with Airplay, but that's likely a network, not an iTunes, issue.
And I have NO idea why OP is so upset about not being able to find a file in iTunes that he used another program to create. Try spotlight, dude.
You have a point.
Let me ask another way: what's missing? What could/should it do that it doesn't?
ETA: I suppose it's just OP's hyperbole that's sticking in my craw. An "unmitigated disaster?" I mean, I know using iTunes is much worse than being told you have inoperable eyeball cancer, but c'mon...
