Do you make it illegal for geographic regions to be part of a contract? When you license a piece of music for a project, does the musician get paid the same for an internal corporate training video as they would for a national TV commercial campaign or for a global Disney film?
One of my favorite TV shows from my childhood is WKRP in Cincinnati. That show was set in a radio station and so there was a lot of music in it. As I understand it, that music was licensed for broadcast TV and so if you buy a DVD set or if a streamer licenses it, they swap out the music because the home video and streaming rights were never secured.
Geoblocking feels like the same kind of problem. Things destined for a smaller audience pay less for licensing.
