This would definitely help for developers who want to use popular copyrighted assets, but it wouldn’t really do much for radio users, as the game creator can only play audio which they own or can get from the marketplace, and radio users are locked to using whatever audio is allowed for the game creator.
If there was a way for Roblox to permit audio that a radio user owns and the game creator doesn’t, that could actually really help. It could work by firstly checking if the user is in the current server, then check for ownership. If both check out, then the audio can effectively load. If the user leaves, then the audio expires immediately.
Considering how the profits of assets tend to be cut by extreme amounts, this kind of audio would have to give around 90% of the profit from the audio to the artist, and that profit would have to be immediately converted to a real currency like USD, as these artists don’t really concern themselves about a digital currency which get cut in many different ways and directions.
