There certainly exists a flow chart about how board-set rates and other aspects of copyright are adjudicated. When there's a public role in those, it can get quite complicated, in terms of the mechanical right, the reproduction right, the performance right and other sorts of rights. It does exist, in some regard, of how that all flows through.
There is also a significant amount of copyright that's negotiated directly between those who own the rights and those who seek to utilize or draw upon those rights. In many cases, that information is proprietary and held within.
Is it possible to understand, for instance, on a board-set rate, how a musician or a photographer or a choreographer may be remunerated for their work? The answer is yes.
In the case where it's potentially engaging with a third party in terms of the distribution within a given contract—what an artist makes from Spotify or from any of the other platforms—that's more complicated, because much of that is proprietary and is a function of the marketplace in terms of how they negotiate those rates.
