Excellent explanation. But to complicated matters further, your description applies mainly to European licensing. The US music publishing workflow is different. In the US, there is no CMO. After agreeing to a license, music publishers send their composition (word-and-music) catalog information directly to Spotify. There is no requirement that they need to send the associated recording with their musical composition. So the burden is on Spotify to match the composition up with the recording to recognize if the recording's underlying composition is licensed. (The recording is licensed because the actual audio file was sent to Spotify by the label). So then Spotify needs to tie all this data together. Compositions can be owned by 5 publishers, who are all sending separate catalog files. Again, no requirement to send an unique identifier to tie these all are up. So Spotify does the best it can to associate all this data to figure out if a recording is licensed, but ultimately, they cannot verify millions of tracks. So they make business decisions that carry risk so people can listen to music. They can say, if we have 90% ownership, we will treat it as licensed or some other deviation from affirmatively knowing every copyright owner without a doubt. So then the music publisher finds a handful of tracks that slipped through and were unlicensed. And they sue. And technically, those tracks were unlicensed, but its not for lack of trying from Spotify. And no music industry player is helping solve the metadata standards or systemic issues. They just lie in wait and sue for money or as a negotiation tactic. And they exploit the "Spotify is ripping off artists" narrative, when in reality, Spotify is working very hard and investing a lot of money to pay out artist and writers properly. These lawsuits are very dishonest, but legally defensible. There are not in the spirit of any productive working relationship with the MAIN distribution channel of your product!
