You can have the best song of the year, millions of plays and a clean contract. And still lose money. How? Through a tiny error in a code almost nobody checks. Metadata is the boring detail that decides whether your money reaches your pocket or gets lost along the way. Let us explain it simply, because understanding it is the first step to getting it back.
🏷️ What is metadata? (explained simply)
Imagine your song is a parcel travelling through the mail. Metadata is the label with your name and address on it.
If the label is written correctly, the parcel (your money) arrives at your house. If the address is wrong, or the postcode is missing, or it has somebody else’s name on it, the parcel gets lost or handed to a stranger.
That is metadata: the label on your music. And in this industry there are several labels that have to match perfectly.
#️⃣ The codes that decide who gets paid
These are the main ones. You do not need to memorise them, just know they exist and that they need to be right:
- ISRC: the unique code for your recording (the master). Every version of a song has its own. It is the fingerprint of that specific recording.
- ISWC: the code for the composition (the lyrics and the melody), separate from the recording. Remember: master and composition are two different rivers of money.
- IPI/CAE: your identity number as a songwriter or author with the collecting societies. It is your ID card in the publishing world.
- Splits: the percentages of who takes what. If three people wrote the song, the splits say how it is divided.
- Titles: it sounds silly, but if the title on streaming does not match the registered title, the money may not match up.
When all of this data matches, the money flows. When just one of them fails, the problems start.
📦 How one error sends your money to the black box
The black box is the fund where money that cannot find its owner ends up. It is not that somebody is stealing it from you out of malice: the system simply does not know it is yours, because the label is wrong.
Think of it this way: there is a mountain of money waiting, and your name is not on the list because your code is misspelled. The money is there. It just cannot find you.
This problem is huge and verifiable: in the United States, the body that administers mechanical royalties (the MLC) received historical unmatched royalties for an adjusted total of $397,286,418.71 — in large part because of data and metadata problems — and its official dashboard (Sep 2026) says it has already matched over 80%. Hundreds of millions waiting for somebody to fix their label.
❌ The typical errors (check if you have any)
These are the trip-ups we see over and over:
- Your name written two different ways. “Juan Pérez” in one place and “J. Perez” in another. To the system, those are two different people.
- The same title across several versions. If “My Song” and “My Song (Remix)” have crossed data, the money gets confused.
- Splits that add up to more than 100%. If three people claim 40%, 40% and 40%, that is 120%. The system does not know who to believe and sometimes freezes everything.
- Missing ISWC or IPI. Without the composition code or your writer number, your publishing can end up orphaned.
- The master registered under the wrong name. If the ISRC points to another entity, those neighboring rights go somewhere else.
Any of these sends your money to the black box or, in the worst case, to the account of somebody else whose data is in order.
🔍 How to check and fix your metadata
The good news: checking metadata is one of the cheapest things you can do, and one of the ones that recovers the most money. Here is the simple plan:
- Gather your codes. Find your ISRCs, ISWCs and IPI. Your distributor and your society have them.
- Compare names and titles. Make sure your name is spelled EXACTLY the same everywhere. A practical tip: keep the title as it appears on streaming, so the money matches what people are listening to.
- Add up your splits. They have to come to 100%, no more and no less. If they come to 120%, there is an error to fix with your co-writers.
- Confirm who owns what. The master and the composition must be registered to whoever they really belong to.
- Fix it at the source. Changes are made where the data was born: your distributor, your PRO, your collecting society.
You do not need to be an expert. You need to check calmly, one detail at a time.
🌉 The bridge between understanding and recovering
Fixing metadata is exactly the bridge between “now I understand how it works” and “I am getting my money back”. There is no point knowing the black box exists if you never check whether you have money trapped in there because of a wrong code.
And this is where you can start without spending or risking anything.
