The Black Box Is About To Be Emptied

From early 2027, the MLC begins its congressionally mandated market share distributions. Each month, it releases one month of remaining 2021 blanket royalties — starting with January 2021, expected to be just under $7 million — allocated pro-rata based on actual distribution data, with interest at the statutory rate.

In plain English: the black box gets emptied one month at a time, and every song that earned royalties in that month receives a slice of the leftovers.

Read that again from a different angle. This is a transfer of wealth from rightsholders with data problems to rightsholders with market share. A publisher holding 2% of the market passively receives something in the region of $129,000 a month during 2027 — money that, by definition, belonged to somebody else and couldn't find its way home.

And here is the part that should make you uncomfortable: once a month's distribution is made, claiming for that month closes forever. Right now, unclaimed shares can still be claimed with all back royalties and interest attached. From 2027, that stops being true one month at a time. A six-year grace window — twice the statutory minimum, to the MLC's credit — becomes a hard deadline on a rolling schedule.

It's fashionable to dunk on collection societies. I'm not going to. Standing up a national mechanical licensing collective from zero — ingesting usage from every DSP, building a centralized works database, and then publishing the whole thing where anyone can search it — is genuinely hard, and the MLC has largely delivered on what the Music Modernization Act asked of it.

More than that: the MLC did something almost no collective anywhere in the world does. It showed everyone the money. It published the data. And then it built the tools to act on it — bulk submission for high-volume, low-value matching, and a targeted matching tool inside the Portal for high-value, low-volume issues. Transparency plus actionability. Most societies offer neither, or at best one without the other.

It also deliberately held off on pro-rata distributions. That was a choice, and a good one. It gave publishers years to clean their data before the incentives changed.

That grace period is what's ending. Not the good behavior. The grace period.

The terminology matters here, because there's no standardized industry glossary and publishing is full of nuance that gets misread.

Unmatched royalties are royalties for recordings reported by DSPs that haven't been linked to any song in the MLC's database. Nobody knows yet whose they are.

Unclaimed royalties are subtler. A recording may be matched to a song, but less than 100% of that work's shares have been claimed by members. The money knows where it belongs. The owner just hasn't turned up.

There are also two separate pots. Blanket royalties are what the MLC collected itself under the blanket license since January 2021. Historical royalties are the ~$397 million that 21 DSPs transferred over in 2021, covering unmatched usage going back to 2007. The 2027 distributions start with the blanket pot, 2021 usage first. The historical pot follows later.

Hold two numbers side by side: a 94% match rate, and 11.4% of the dollars still without an owner. Both are true. Match rates count usage matched to works. The unclaimed pool also contains money for works that are matched but whose shares sit unclaimed. The gap between those two figures is exactly where you should be looking.

Under a pure usage-based system, the question was simple. Is this recording linked to this work? Are my shares registered? Did the money flow?

Under a pro-rata system, the question changes shape entirely. Is my data complete relative to the rest of the market?

When distributions are proportional, your share of the pie is no longer just a function of your own data. It's a function of everyone else's too. If your catalog is under-matched or misattributed, you're not just missing revenue in isolation — you're losing share.

That's the shift nobody has internalized yet. "Is my data good enough?" becomes "Is my data cleaner than everyone else's?"

Identification exposes problems in isolation. Allocation exposes them relative to the market. It is a completely different game with completely different stakes.

Multiple registrations for the same work, usually caused by inconsistent metadata combined with parallel submissions from different parties. A title with a feature credit. A remix filed as a new work. A writer name spelled two ways across two societies.

Duplicates quietly split or block income. Even when everything looks correct at surface level, they dilute earnings in ways almost impossible to detect without systematic analysis — because each individual registration looks fine.

Before 2027, duplicates were an admin annoyance with a revenue cost. After 2027, they're structural. A duplicated registration fragments matching and muddies the exact distribution data that pro-rata allocations are calculated from. You don't just lose the direct income — you shrink the market-share denominator you'll be measured against for every leftover dollar.

The most visible category, and the one most talked about. If a recording isn't linked to a work, the royalties have nowhere to flow. For a society that licenses digital mechanical usage exclusively, that's fatal to the payment.

In an identification-based system, that's a missed payment. In a pro-rata system it's also a reduction in relative share — twice punished.

The MLC's framing is that what remains is small change: fewer than 5% of remaining unmatched recordings have accrued more than $1, and the rest average five to six cents each. That's accurate. It's also exactly the point. Small claims at scale are the goldmine. Pennies multiplied by millions of instances is how you get to $77 million.

No human team can economically chase a five-cent claim. Tooling can. That asymmetry is the whole opportunity.

Less obvious, harder to value, and more damaging than unmatched. These are cases where recordings are already matched — to the wrong works.

The data looks complete. Complete does not mean correct. In aggregate, these misallocations distort distributions in ways that are very difficult to unwind after the fact.

And this one compounds worst of all under pro-rata. If somebody else is already collecting your identified money, they will also receive an inflated allocation of the unidentified money. The error pays them twice and costs you twice.

Even where works are correctly registered and recordings correctly matched, shares go unclaimed. Missing co-writer data. Unresolved conflicts. Gaps in representation. A publisher who never confirmed the link.

These gaps don't just delay income — they stop it, or worse, redirect it. We regularly surface percentages that aren't merely unclaimed but claimed by the wrong rightsholder entirely.

This is the category that should terrify you most, because it's the easiest to fix and the most expensive to ignore. Matched-but-unclaimed shares are the cheapest revenue you will ever recover. They come with back royalties and statutory interest attached. And they evaporate on a schedule starting in 2027.

Every problem above has the same origin: the same song described differently in different systems. Title punctuation. Featured artist handling. Writer legal names versus performing names. Missing IPIs. Missing ISWCs. ISRCs that live in the distributor's system and were never handed to the publishing side.

Small inconsistencies don't stay small. They fork into duplicates. Duplicates break matching. Broken matching leaves shares unclaimed. Unclaimed shares get pooled. Pooled money gets redistributed by market share.

That's the whole chain. It starts with a comma and ends with somebody else's bank account.

The public dashboards tell you the size of the pool. They don't tell you whether your catalog is a net receiver or a net donor. Here's what shows up when you look properly.

A recent client with a significant catalog had 9.5% of their entire catalog carrying material work-level issues at the MLC — underclaimed works measured against their own internal catalog expectations, plus duplicated registrations. That figure alone would justify the exercise.

The more startling number: 58% of their works had no ISRCs matched at the MLC at all. Works earning precisely nothing from US mechanicals. Not underpaid. Unpaid.

What's cleanup worth? As a general rule we see a minimum 10–15% collections uplift. One large PRO recently told a client their revenue had doubled over the period of our cleanup — and being honest, as they were, not all of that is attributable to our work. But the direction of travel is not subtle. This isn't growth from new repertoire or better deals. It's money that was always owed, finally arriving.

Private equity. Sovereign funds. Publishers. Family offices. Everyone is buying music.

They are not buying songs. They're buying predictable cash-flow assets.

That distinction is everything, because a cash-flow asset has to be documented to be underwritten. Ownership alone doesn't clear diligence. Ownership has to be verified, evidenced, correctly registered, and demonstrably collecting. A song you own but cannot prove you own, in a system that isn't paying you for it, prices as a discount and a risk, not an asset.

The catalog boom made metadata a valuation input. The 2027 distributions make it a yield input. Those are two independent reasons your registrations now sit on a balance sheet rather than in an ops folder.

How confident are you, honestly, that your catalog is clean?

Have you ever compared your registrations across every society you're a member of — line by line, not spot-checked?

Have you ever searched your own catalog for duplicate works?

Have you verified that every work totals 100% claimed, with the right parties on the right percentages?

How many of your recordings are unmatched right now?

How much money is sitting in a place you don't know exists?

Most artists — and plenty of labels and publishers — cannot answer a single one of those. That's not a character flaw. Nobody taught them. But in 2027 the answers get priced whether you know them or not.

Artists spend years learning algorithms. Almost nobody learns ownership.

There are a thousand courses on hooks, thumbnails, playlist pitching, and posting cadence. There is nearly nothing on how a work gets registered, how a share gets claimed, or how a recording gets linked to a composition. So the industry produces very sophisticated marketers who own very little.

Everyone wants streams. Very few build assets. Marketing gets attention. Infrastructure builds wealth.

I've spent more than a decade inside that infrastructure — the unglamorous half of the business. While the conversation moved to growth hacks and content strategy, I stayed on the plumbing: registrations, splits, matching, catalog structure, valuation. Every single catalog I've cleaned has surfaced something. Missing money. Incorrect ownership. Broken registrations. Duplicate works. Disconnected recordings. Revenue leaks nobody knew were open.

I have never once found a perfect catalog. Not one.

Stop filing this under admin. Metadata is financial infrastructure.

It is ownership infrastructure — the record of who controls what. It is asset protection — the thing that stops your rights drifting to a stranger's account. It is estate planning — what your family inherits is only what's documented. It is investment readiness — no buyer underwrites what they can't verify. It is catalog valuation — multiples move on the quality of the data. It is royalty optimization and, eventually, future liquidity.

Your metadata directly determines what your catalog sells for, whether it can be licensed cleanly, whether an investor will touch it, whether it transfers to your estate intact, and how much of what you earn actually reaches you.

Nothing about that is administrative. That's the balance sheet.

It isn't complicated. It's just work nobody does.

One: reconcile your internal catalog against what the MLC actually holds — registrations, shares, duplicates. Not what you assume is there. What's there.

Two: claim the matched-but-unclaimed shares. With interest attached, this is the cheapest revenue you will ever recover, and it has an expiry date now.

Three: investigate unmatched recordings at scale. Five-cent claims only make economic sense with automation, so use the bulk submission path and reserve the Portal tool for the high-value titles that justify human attention.

Four: resolve duplicates before they quietly reshape your share of every distribution to come.

Do it in that order. Do it before the first monthly distribution lands.

This is the part where most people expect a pitch. Here's the honest framing instead.

A catalog audit is not consulting. It's an inspection before a disaster. You don't buy a house without one. You don't buy a used car without a CarFax. No fund acquires an asset without diligence. Yet artists and independent publishers hold seven-figure income streams and have never once looked under the floorboards.

An asset health assessment tells you three things: what you actually own, what's actually registered, and where the gap between those two is costing you money. Everything else — claiming, correcting, restructuring — is downstream of seeing it clearly.

You cannot optimize what you cannot see. And in 2027 you cannot claim what you didn't look for in time.

A year ago the conclusion was that the value was hiding in the gaps between datasets, waiting to be connected. Still true. What's changed is the deadline. Those gaps are about to be monetized — just not necessarily in your favor.

The MLC did the hard part. It showed everyone the money, published the data, and built the tools to fix it. After six years, redistributing the leftovers is defensible. The rightsholders who lose out in 2027 won't be able to say they weren't warned. The warning has been sitting on a public dashboard the whole time.

In 2027, every publisher will be on one side of the market share distributions: collecting their own money, or quietly collecting everyone else's.

Your next release matters. The catalog you've already built may be worth far more than the thing you're about to put out. The question is whether you actually know what condition it's in.

If you don't — start there.
