I've just accepted that this will never happen, and that as long as blacks make music, whites will steal, copy, and pass it off as their own. Hell, rock music used to be super black, now when you think about it you can only think about white people (and Jimmy). Rap is gonna be the same way eventually.
It makes sense, most white people love ironically using black slang, but they don't actually like black people. It's just easier to have a white artist that that "acts black" so you can enjoy the music without having to listen to a "thug"
They have the largest demographic so they will always commoditize and whiten everything
That's not the issue, more so, is it possible for us to create a new genre of music? I'd say no because White people are "meta" and aware of Black American prowess for creating music and with that new awareness, they'd cash grab any innovative thing we came up with..
The Internet has integrated us all and White people have access to our culture in a way they wouldn't back in the day unless they went to our hoods, parties, music stores, etc
