Once the User API is launched (expected in Dec 21) then we'll finally be able to automate profile and catalog creation for the many distributors standing by. Expecting 20-50X in catalog size then.
We're about to launch an long-anticipated User API which is going to solve this double account type problem (listener + artist + etc). Supposed to drop in December.

TBH I just liked the number 9. Subtle Beatles reference I guess. But the model also reflects the process of falling in love with an artist or an album, meaning the payout to the artist goes up the more I repeat listen.
