How to Claim Your Share of the MLC's $424M Black Box Pool (2026 Walkthrough)

Quick Answer

The Mechanical Licensing Collective (MLC) received $424,384,787 in accrued historical "black box" mechanical royalties from digital streaming services in 2021, the largest one-time songwriter royalty transfer in U.S. history. Most of that pool has been matched and paid out, but new unmatched royalties accrue every month, and as of the January 2026 distribution The MLC was still holding the residual from January 2021 usage. Self-published and indie songwriters who never registered with The MLC are the single largest group missing money. According to Chartlex campaign data from 2,400+ campaigns, more than 60% of independent artists running active Spotify promotion have never created a Member account at themlc.com, which means their U.S. mechanical royalties from Spotify, Apple Music, Amazon, and YouTube are sitting unclaimed. Registration is free, takes about 30 minutes, and unlocks retroactive payouts back to January 2021.

What the Black Box Actually Is

When a song streams on Spotify, Apple Music, Amazon, or YouTube inside the United States, the streaming service owes a mechanical royalty to whoever wrote the song. If the streaming service cannot identify the songwriter or publisher, that royalty becomes "unmatched." Before 2021, those unmatched dollars piled up inside the streaming services with no central authority to claim them.

The 2018 Music Modernization Act created The MLC to fix exactly this problem. Streaming services were ordered to hand over every unmatched mechanical royalty they had been holding, then route all future U.S. mechanical payments through The MLC for matching and distribution. The first transfer in February 2021 totaled $424,384,787, with $42M coming from Amazon Music and over $32M from Google/YouTube alone.

Why Self-Published Songwriters Are Still Owed Money

The MLC has done aggressive matching work and the original 2021 black box pool is mostly gone, with under $7 million remaining from January 2021 usage as of early 2026. The bigger ongoing opportunity is the new unmatched royalties that accrue every single month from current streams.

If you wrote a song, released it through DistroKid, TuneCore, CD Baby, or any distributor, and never registered the composition with The MLC, your mechanical royalties on every U.S. stream are accruing unmatched right now. Your distributor handles the recording side, not the songwriter side. Those are two completely different revenue streams, and most independent artists only collect one of them.

MLC vs PRO vs HFA vs Distributor: Who Pays What

The biggest reason songwriters miss MLC money is confusing it with the royalties their PRO or distributor already pays. Here is what each entity actually covers.

Your distributor pays you as the artist on the recording. Your PRO pays you for performances of the underlying song. The MLC pays you the U.S. digital mechanical, which is a separate bucket that did not exist in any organized form before 2021. If you only collect from your distributor and your PRO, you are missing the third leg of the songwriter royalty stool.

ISRC vs ISWC: The Code That Actually Matters Here

This trips up almost every first-time MLC registrant. An ISRC identifies a specific sound recording. An ISWC identifies the underlying composition. The MLC matches royalties to compositions, which means ISWC is the code that drives your payouts, not ISRC.

You do not need an ISWC to register with The MLC, but supplying one (or letting The MLC assign you one) dramatically improves match rates against streaming usage data. When a streaming service reports usage to The MLC, the matching engine tries to link the recording to a registered composition. Without a clean ISWC link, your song can sit in unmatched status for months even after you have a Member account.

The 2026 Claim Process: Step by Step

The MLC calls registration "Connect to Collect." It is free, fully online, and takes roughly 30 minutes if you have your catalog list ready.

Step 1: Confirm You Are Eligible

You qualify if you wrote (or co-wrote) any musical composition that has been or will be streamed inside the United States, you own at least some of the publishing share, and you have not signed that share over to a publisher or admin company. Self-released artists who write their own songs almost always qualify for at least a partial share.

Step 2: Search the Missing Member Lookup First

Before signing up, search The MLC's Missing Member Lookup at themlc.com. This is a public database of rightsholders The MLC has identified as likely owed money but who have not yet registered. A hit confirms you have unclaimed royalties waiting and gives you a reference number to speed up enrollment.

Step 3: Create Your Member Account

On themlc.com, click "Connect to Collect" and start the signup flow. You will provide personal identity information for verification, set a username and password, and answer questions about your role with respect to your songs. Self-administered songwriters get routed to the Member Hub. Songwriters whose catalog is partially handled by a publisher get routed to the Songwriter Hub instead.

Step 4: Build Your Publisher Profile

Even if you have never registered as a publisher, The MLC requires you to set up a publisher entity (it can simply be your name doing business as your songwriter name). This entity is what receives payments. You will provide W-9 information, a payment method (ACH or check), and tax residency details.

Step 5: Register Every Composition

This is the centerpiece of the process. For each song you have written, you submit:

1. Composition title
2. All co-writers and their ownership splits (must total 100%)
3. ISWC if you have one
4. At least one linked ISRC for each recorded version
5. Original release date and any alternate titles

You can register songs one at a time in the portal or upload a bulk catalog via CSV. The bulk template is the fastest path if you have more than 10 songs. Ari's Take has a step-by-step songwriter walkthrough that mirrors The MLC's official guidance and is worth bookmarking.

Step 6: Resolve Conflicts and Disputes

If two parties claim overlapping shares of the same composition, The MLC flags it as a conflict and freezes payouts on that song until resolved. Conflicts usually appear when a co-writer registered first with different split percentages. The portal includes a dispute workflow where you upload supporting documentation (split sheet, signed agreement) and The MLC mediates.

Step 7: Watch the Payment Schedule

The MLC distributes monthly. Royalties from a given usage month are typically paid out roughly two months later, after streaming services report and The MLC matches. Your statements appear inside the Member Hub with a usage breakdown by service. Retroactive payouts on newly matched historical usage land as a one-time catch-up payment.

Claim Process Quick Checklist

Use this checklist to move from zero to first payout without skipping a critical step.

If you run promotion campaigns and want to know what your stream volume should translate to in actual songwriter earnings, plug your numbers into the royalty calculator or the Spotify calculator before you register so you have a baseline expectation.

What You Can Realistically Expect to Collect

U.S. digital mechanical rates under the current statutory rate sit around $0.0008 to $0.0012 per stream, paid to the songwriter side. That number is small per stream but adds up fast on any song with consistent playlist placement or back-catalog volume. A song with 500,000 U.S. streams generates roughly $400 to $600 in mechanical royalties, paid through The MLC, that you collect on top of whatever your distributor pays you for the recording.

For reference on the recording side, our breakdown of how much Spotify pays per stream in 2026 covers the master recording rate, and our Spotify royalty calculator: real math post separates the master and publishing components clearly.

When You Need an Admin Instead of Going Direct

Going direct with The MLC works well if you control your full publishing share, write only your own catalog, and are comfortable managing registrations yourself. If you have international ambitions, sync placements, or co-writes with major-label writers, a publishing admin company (Songtrust, CD Baby Pro, Sentric, others) can collect MLC money on your behalf and also handle international societies you cannot reach directly.

We cover the tradeoff in detail in our music publishing for independent artists guide and the more advanced music publishing administration breakdown. The short version: if you only release in the U.S. and write your own songs, direct MLC registration captures most of the value. If you collaborate, sync, or chart internationally, an admin earns its 10-15% commission.

Pairing MLC Income with Promotion

Mechanical royalties scale with stream volume. The reason most indie songwriters dismiss The MLC as "not worth the paperwork" is that their stream counts are too low for the math to feel meaningful. That changes once a song gets into rotation.

If you are running playlist promotion or considering it, our campaign plans page lays out the stream volumes typical for each tier, and the free audit tool checks whether your current setup is leaking money before you spend on growth. Combine consistent playlist placement with proper MLC registration and you start collecting from both sides of every U.S. stream, not just the recording side.

For the performance royalty piece (the third major bucket), our performance royalties: how to collect in 2026 post covers ASCAP and BMI signup, which you should complete in parallel with your MLC registration.

Frequently Asked Questions

Is The MLC free to join?

Yes. The MLC is funded by an administrative assessment paid by streaming services, not by songwriters. Membership, catalog registration, dispute handling, and payout processing carry zero fees for the songwriter or publisher. Beware of any third party charging an upfront fee to "register you with The MLC," because the official process at themlc.com is always free.

Can I claim royalties from before I registered?

Yes, with limits. Once you register and match your compositions to historical usage data, The MLC will pay out retroactively for any matched usage going back to January 2021. Older pre-2021 mechanicals were settled separately under the MMA's historical unmatched royalty transfer and are not individually claimable through new registrations today.

Do I still need ASCAP or BMI if I sign up with The MLC?

Yes. The MLC handles U.S. digital mechanical royalties only. ASCAP, BMI, and SESAC handle performance royalties from radio, TV, live venues, and streaming, which is a separate revenue stream. You need both. Most working independent songwriters end up with ASCAP or BMI for performance plus The MLC for mechanical, and that combination covers the U.S. domestic basics.

What happens if my co-writer registered our song first with wrong splits?

The MLC will flag the overlap as a conflict and freeze payouts on that composition until both parties agree on splits. You file a dispute through the Member Hub, upload your split sheet or written agreement, and The MLC mediates. Do not skip getting a written split sheet at the time you write any song. It is the single best protection against frozen royalties later.

How long after registering do payments start?

Once your account is live and compositions are registered, matching begins on the next monthly cycle. Most members see their first payout 60-90 days after registration, covering whatever usage has been matched in that window. Catalog-wide retroactive matches can take 6 months or longer to fully process, especially for older songs without ISWCs.

Does my distributor (DistroKid, TuneCore, CD Baby) already collect this for me?

No, with one exception. Your distributor pays you the master recording royalty for the recording, not the songwriter mechanical for the composition. TuneCore offers an opt-in MLC partnership that can route your mechanicals to them, and CD Baby Pro acts as a publishing admin. Standard DistroKid does not collect U.S. mechanicals on your behalf, so DistroKid users almost always need to register directly with The MLC.

What if I co-wrote a song with someone signed to a major publisher?

Register your share only. Major publishers handle their own writers' shares directly with The MLC, so you only need to claim your percentage. List the co-writer accurately and indicate that their share is administered by their publisher. The MLC's matching engine handles the split routing automatically once both sides are registered.
