Isn't that the YouTube premium model? You pay a fixed monthly fee, Google takes a cut and the rest is divided among the channels you watch. It's supposedly in proportion to the watch time you've allocated to each of them, but I'm not sure that's ever been confirmed.

EDIT: this is indeed the Spotify model while youtuve's approach was to treat premium as a make up for missinflg ad watches so pays out from the individual viewers subscription.
