Five systems hold your music money. When one doesn't match, that slice just sits there.
Nobody sends you one check that adds it all up. Here's the whole map — so you can see where a slice might be stuck.
Every song is two properties
Before you can track the money, you have to see that one song is really two things. The composition is the writing — the song itself, the publisher side. The sound recording is the master — the actual recorded version, the artist and label side. Each one earns on its own, gets registered on its own, and pays out through its own systems.
Five systems, one song feeding all of them
Those two properties get paid out through five different systems. Three sit on the composition side, two on the recording side. Not one of them talks to the others, and not one of them sends you a combined statement.
The other four keep paying — so nothing looks broken
Here's the trap. A mismatch in any one system strands only that system's slice. The other four keep paying like normal. So you glance at your distributor statement, see streaming money landing, and everything looks healthy — while a different system quietly holds a slice that has nowhere to go.
$0 collected on works that were live and getting played
We saw this in our own house. Our HFA / publisher-admin statements read $0 collected on works that were live and getting played. The license existed. The plays were real. The match didn't — so the system had nowhere to land the money, and it just sat there while every other statement looked normal.
Same true info in all five
The whole game is consistency. Income can only land where there's a registration to land on, and it finds that registration by matching identifiers. So the same true info has to read the same way in every system: the ISRC on your recording, the ISWC on your composition, your IPI number, the exact titles, and the writer and publisher splits. Line those up across all five and the money has a home. Leave one system out of step and that's your leak.
Register and collect only on your own real work — your compositions, your masters, your splits. Claiming a slice of someone else's song to grab its money is fraud, full stop. This page is admin education, not legal or financial advice, and every system's rules and policies vary. And if someone else is claiming your work — a disputed writer credit, a master you don't recognize being collected on — that's an ownership dispute. Don't try to self-serve your way through it. Take it to a music attorney.
See if your five systems actually agree
Walk your own catalog through the same map, one system at a time, and check whether the identifiers match everywhere they need to.
No promises about numbers. Just clean data across every system, so what you're owed can find you.
