Missing money doesn't announce itself. No statement arrives saying "you were not paid." The company sees the money that showed up, and has no systematic way of knowing what should have shown up. That gap is where independent labels and music companies can quietly leave substantial revenue uncollected.
I spent years as a transactional attorney watching this happen from the inside. The same five failures, over and over, at companies of every size. Here they are, in plain English, with the tell for each one so you can check your own catalog.
1The work was never registered.
Every royalty stream depends on accurate ownership and payment data reaching the right distributor, society, or licensing organization. On-demand master-recording revenue usually reaches a label through its distributor. Other recording income, including US non-interactive digital-performance royalties, may flow through organizations such as SoundExchange. Composition revenue travels separately: US interactive-streaming mechanicals through the MLC, and performance royalties through organizations such as ASCAP and BMI. If a work was never registered with the right organization, they don't send the money to the wrong person. They hold it, and wait.
The scale of this is public, and to the MLC's credit, so is the data. The MLC reports an adjusted historical pool of approximately $397.3 million in unmatched royalties, of which approximately $238.2 million has already been matched and paid out. It makes data on unmatched uses and unclaimed shares searchable through its free Member tools. But roughly $159 million remains undistributed, not because anyone is hiding it, but because claiming it requires knowing your catalog's data well enough to find it. Federal law provides for an eventual equitable-market-share distribution of unclaimed accrued royalties, under which larger rightsholders generally receive larger allocations. The MLC intends to begin that process in 2027 with certain royalties from 2021 blanket-license usage. It has not announced a market-share distribution from the historical pool discussed here.
The tell: your recordings are earning, but the songwriting side of the same songs shows little or nothing.
2The databases can't recognize your song.
Registration isn't enough if the data doesn't match. Your song exists in one database as "Song (feat. Artist)" and in another as "Song." A writer's ID number got detached at a society. An ISRC, the unique code that identifies a recording, never got linked to the composition it embodies. Inconsistent titles, missing identifiers, and incomplete contributor data can prevent or delay a confident match, especially when several discrepancies occur together. Money for a song the systems can't confidently identify is money that doesn't move.
The tell: some versions of a song get paid and others don't, and nobody can explain why.
3The shares were never claimed.
Sometimes the song is registered and matched, and the money still doesn't arrive, because the ownership shares on file are incomplete. A writer is registered at ASCAP but the publisher share sits unclaimed. Splits were agreed in a text thread after the session and never filed anywhere. A co-writer's publisher claimed their half and nobody claimed yours.
Societies pay the shares they can see. The rest waits, and in some cases it eventually stops waiting.
The tell: a society is paying someone on the song, just not you, or paying you a smaller share than your agreement says.
4A transition broke the pipeline.
Labels switch distributors. Distributors get acquired, merge, or shut down. Catalogs migrate. And in every one of those transitions, payment pipelines can silently break: a payee gets dropped, a batch of tracks doesn't survive the migration, a territory stops reporting. The music keeps streaming. The revenue may continue accruing, become misallocated, or sit in suspense. It just stops arriving.
This one is brutal because nothing looks wrong. Listening holds steady while revenue falls off a cliff, and unless someone is comparing those two lines, the company just experiences it as "streaming pays less than it used to."
International collection adds another layer. Reciprocal agreements often allow a writer's home society to collect through foreign partners, so separate registration in every country is usually unnecessary. But missing ownership, mandate, or work data can still interrupt the path home, and societies apply different claim and distribution rules.
The tell: revenue dropped and your streams didn't, especially in the months after changing distributors.
5The statement math is wrong.
The money that does arrive deserves scrutiny too. Distribution fees have a way of drifting above the contract rate. Deductions appear that no agreement provides for. Reserves get withheld against returns and never come back. Recoupment balances decline slower than the arithmetic says they should.
None of this requires bad faith. Paying systems are built to process enormous volumes at scale, not to audit each statement from the recipient's perspective. But every one of these errors compounds monthly until someone puts the contract next to the statement and does the math.
The tell: honestly, there usually isn't one you can see, which is exactly the problem. Fee percentages that don't match your agreement are the easiest place to start.
What to do about it
You can check some of this yourself, and you should: use the MLC's own Claiming and Matching Tools, which are free, compare your fee percentages against your distribution agreement, and pull your streaming analytics next to your revenue for the last two years.
Or you can have us do it. Cadence audits independent catalogs against all five failures, using your contracts as the governing baseline for fees, deductions, recoupment, and payment obligations, then reconciling those terms against catalog data, registrations, usage, and statements. Put in industry terms: we help rights holders identify, claim, and prevent revenue from becoming trapped in the industry's black boxes. There is no upfront audit fee. We earn a percentage of funds actually recovered. If we recover nothing, you owe nothing. Any recovery is money your existing processes had not identified or collected.
Either way, check. No one has more incentive to check than you do.
