Will mainstream music ever be resurrected and BQ?

lolwut? Mainstream music is still very alive, and is making big money. Whether or not they will ever go back to your favorite genre's or style is unlikely since music is always evolving. Does music from the 30s sound like music from the 50s? Does music from the 50s sound like music from the 70s? Does the 70s sound like the 90s, and the 90s like the 10s? Get my point. Music will always sound different as time goes on...
