When the POLR member uploads their work, they will also complete an online form outlaying all the metadata surrounding the work: Composers, artwork, credits, lyrics, bpm, musicians, producer, engineer, etc., and the corresponding percentages that each stakeholder holds in the work. This will be a similar process as registering a song with a Performing Rights Organization, except with more data. The incentive is there to provide all this data because it is how the member will get paid, and will become the universal, official registry for the work on the POLR.
In order to facilitate direct autonomous micropayments to the rights holders of the song, there must be a direct link between the rights holder metadata and the actual audio file itself. This can be achieved in a variety of ways. Through open source audio fingerprinting technology like echoprint, as well as registering the metadata with the audio file’s ISRC code on the blockchain.
Whenever a user streams a song on the POLR, this metadata will be securely identified with the track. This will allow the POLR to autonomously send micropayments in the proper proportions to all the stakeholders in the recording / song.
Eventually an extensive database will form that will provide many solutions to the maze of silos that exist in todays digital music environment. Considering the epic failure of the valiant attempt at global consensus with the Global Repertoire Database, perhaps the only viable solution is to start fresh and build a system from the ground up. Because the POLR is an unowned, open system, it has the potential to evolve to become the officially trusted universal metadatabase for all entities involved in a musical recording / work.
