Black Box Royalties and the MLC Countdown: What Happens to Unmatched Money in 2027

What black box royalties are

Black box royalties are earnings that were collected but could not be matched to a rightful owner. A streaming service reports a song was played and pays for the use. Somewhere in the chain, the ownership data is missing, wrong, or incomplete, so the money cannot be delivered. It waits. The industry calls that waiting pool the black box, and it exists in every collection system in the world, from performance societies to The MLC.

The causes are ordinary. A song released without a split agreement. A writer registered at one society and not another. A title spelled two different ways in two different databases. A producer who contributed to the writing but was never listed. None of these require bad intent. All of them break the match between a use and an owner.

The MLC and the 2021 money

The MLC, the Mechanical Licensing Collective, collects and pays digital mechanical royalties for songs streamed in the United States under a blanket license. When it launched, it received a large pool of historically unmatched royalties from streaming services, covering years of plays that had never been matched to owners. The MLC has spent years working to match that money song by song.

Here is the deadline that matters now. Beginning in early 2027, The MLC is set to start distributing the still unmatched royalties from 2021 by market share, month by month. Market share distribution means the money is divided among publishers and songwriters based on their share of overall matched activity, not based on whose songs actually earned it. Once a month is distributed that way, that month is closed. If your 2021 song is matched afterward, the money for the months already distributed is gone.

Why this should get your attention

Many working songwriters and producers released music in 2021 without complete registrations. Catalogs changed hands. Writers switched societies. Producers went uncredited as writers on songs they helped compose. If any of that describes your 2021 releases, there may be money with your name effectively on it that is about to be paid to the largest catalogs in the business instead, legally and by design.

This is not a reason to panic. It is a reason to audit, and there is still time to act before the distribution begins and while it moves through the year month by month.

A practical audit you can run

First, list every song you wrote or co wrote that was released in or before 2021 and is available on streaming services. Second, confirm each one is registered at your PRO with the correct title, writers, and splits. Third, confirm each work appears correctly in The MLC records, and search The MLC public database for your songs and your name, including alternate spellings and old stage names. Fourth, fix what you find: file corrections, register missing works, and resolve duplicate or conflicting claims. Fifth, look specifically for songs where you were a co writer, because those are the registrations most likely to be missing your name entirely.

Pay attention to producer written songs too. If you produced a record and contributed melody or structure, and the team treated you as a writer at the time, make sure the registration reflects it.

The larger lesson

The black box is not a one time event. Unmatched money builds every month, in every system, wherever registrations lag behind releases. The writers who collect fully are the ones who treat registration as part of releasing music, not as paperwork to catch up on someday. The 2027 countdown is simply the loudest reminder the industry has given in years: money you earned can be reassigned if the record does not show you earned it.

Make sure the record shows it.

Do not limit the audit to 2021 either. Run the same checks on your 2022 through 2025 releases while you are in the databases. Unmatched money from those years is still in the ordinary matching process, where a correct registration today collects it tomorrow, without any market share deadline attached. The countdown applies to the oldest pool first, but the habit it teaches applies to every song you have ever released and every song you will release next.
