The Real Cost of Bad Metadata
Contents
A musician signed to a well-known indie label discovered he was owed roughly $40,000 in royalties across 70 songs. The money had been accumulating for six years — not because his songs weren't being streamed, but because a metadata glitch between industry databases had quietly removed his credits. By the time the error was corrected, the collection window had closed. He never got paid.
The Mechanical Licensing Collective (MLC) in the US alone is sitting on hundreds of millions in historical unmatched royalties — money generated by real streams that can't be connected to the right people. The root cause, in nearly every case, is bad metadata.
What "Metadata" Actually Means for Your Money
Metadata is every piece of information attached to a song that isn't the audio itself. It's the data that tells streaming platforms, PROs, publishers, and collecting societies who made the song, who owns it, and who should get paid.
There are two layers:
Descriptive metadata is what listeners see — song title, artist name, album name, genre, release date. Getting this wrong affects discoverability and can fragment your audience across duplicate artist pages.
Rights metadata is what the payment system sees — and this is where the money lives. It includes:
| Identifier | What It Identifies | Why It Matters |
|---|---|---|
| ISRC (International Standard Recording Code) | A specific sound recording | Links streams to the correct master recording for payment |
| ISWC (International Standard Musical Work Code) | The underlying composition | Links the song to its songwriters for publishing royalties |
| IPI/CAE Number | A specific rightsholder | Your unique ID with your PRO — how they know to pay you |
| UPC (Universal Product Code) | A release (album, EP, single) | Identifies the product at retail and streaming level |
Every one of these identifiers connects a different piece of the payment chain. Miss one, get one wrong, or enter it inconsistently — and money starts falling through the cracks.
How Metadata Flows From Studio to Paycheck
Split Sheet
Agree on percentages, sign with all contributors
PRO Registration
Register the song with ASCAP, BMI, SESAC, etc.
Songview
ASCAP-BMI database cross-references all registrations
Distributor
Upload release with matching songwriter metadata
Royalties
Streaming platforms report usage, PROs distribute payments
Every handoff in this chain is an opportunity for errors. There's no universal standard for how metadata is collected, formatted, or stored — a label's database is different from Spotify's, which is different from ASCAP's, which is different from BMI's. With roughly 106,000 new songs uploaded daily, even small error rates add up to massive amounts of lost money.
The Five Most Expensive Metadata Mistakes
Not all metadata errors are created equal. These five cost producers and songwriters the most money.
1. Never Registering the Composition
Your distributor handles the sound recording — but they don't automatically register the composition, which is a separate copyright with its own royalty streams. To collect composition royalties, you need to register separately with your PRO, The MLC (for US mechanical royalties), and ideally a publishing administrator for international collection.
2. Name Mismatches With Your PRO
Your PRO matches your name in their system to credits on streaming platforms. If those names don't match exactly — even "Jon Smith" vs. "Jonathan D. Smith" — the match fails and royalties sit uncollected. It gets worse with collaborators: if one writer registers the song as 100% theirs and another claims 50%, the PRO will hold ALL money until the dispute is resolved.
3. Wrong or Missing ISRC Codes
The ISRC is the unique fingerprint for a specific recording. Each version (original, remix, acoustic, live) needs its own ISRC. But if you reissue the same recording through a different distributor and get a new ISRC assigned, streaming history and royalty data split across two entries — making both harder to track.
4. Misspelled Names and Inconsistent Credits
Even a single-character typo — "Jonh Smith" instead of "John Smith" — can create a separate artist profile on streaming platforms. Streams split between the correct and incorrect profiles, royalties go to the wrong identity (or nobody), and corrections take days or weeks to propagate. This compounds when different distributors enter the same person's name differently across releases.
5. Missing or Incorrect Split Information
Splits must add up to exactly 100%. When they don't, systems flag the registration and hold payments until the discrepancy is resolved. Without a signed split sheet documenting the agreed percentages, resolving disputes becomes one person's word against another's.
Where Your Unclaimed Money Actually Goes
When royalties can't be matched to rightful owners, they enter the "black box" — unmatched royalties held by collection societies, publishers, and DSPs worldwide. Societies hold these funds for 2-3 years, then redistribute them to existing members weighted by market share. Your royalties can literally end up in a major-label artist's pocket.
The MLC received $426.7 million in historical unmatched royalties — only about $29.5 million has been successfully matched and paid out. CISAC's 2025 report shows global music royalty collections hit €12.59 billion in 2024, and up to 25% of publishing royalties are misdirected or never reach the right people.
What This Costs You Personally
If your compositions aren't properly registered, every stream generates publishing royalties that go uncollected. The more songs in your catalog and the more platforms they're on — Spotify, Apple Music, YouTube, Amazon Music, radio, TV, film — the faster those missed payments add up.
How to Fix Your Metadata
Most metadata problems are preventable. Here's what to do at each stage.
Before the session — Join a PRO and note your exact registered legal name. Get your IPI number. Register with The MLC if you're US-based. Have a split sheet template ready.
During the session — Document credits in real time (don't rely on memory). Agree on splits before you leave. Collect legal names, PRO affiliations, and IPI numbers from every collaborator.
At distribution — Spell names exactly as registered with each person's PRO. Use a unique ISRC for each distinct recording. Don't assume your distributor handles publishing — register the composition separately with your PRO and The MLC.
After release — Verify your credits on streaming platforms within a week. Check The MLC's portal for unmatched royalties. Search your PRO's database to confirm registration. Consider a publishing administrator for international collection.
The System Is Improving — But the Burden Is Still on You
The MLC has matched over 90% of ongoing royalties from its launch forward. The UK government published official metadata standards in 2025. New platforms like Notes.fm have identified over $10 million in missing royalties during beta alone.
But there's still no universal standard, no single database, and no requirement to verify accuracy before a song goes live. Every song you release without complete, accurate metadata is a bet that the system will figure it out. The data shows it won't.
