MLC Black Box Royalties: What the $7 Million Monthly Distribution Means

Starting in April, music publishers will begin receiving roughly $7 million per month in royalties they did not earn through any new deal or release. This is the first market share distribution ever executed by the Mechanical Licensing Collective, the body created by the 2018 Music Modernization Act to serve as a middleman between streaming services and the songwriters and publishers owed mechanical royalties. If you write songs, publish them, or work anywhere near that part of the industry, this is a process worth understanding.

The money being distributed is what the industry calls "black box" royalties. Officially, the MLC refers to it as "unmatched" or "unclaimed" royalties. It is money that streaming services paid out for song usage in the U.S. that could never be linked to a verified rights owner. Sometimes that happens because an independent songwriter released music without supplying complete metadata. Sometimes it is a clerical error on the part of a well-known, well-resourced act. Either way, the money sat in a pool with nowhere to go.

The MLC is required by law to spend at least three years attempting to match unclaimed funds to their rightful owners before redistributing anything. Now, having crossed that threshold for the royalties accrued from January 2021 onward, the organization is ready to begin releasing those funds. The monthly distributions will start with the January 2021 pool and continue month by month. At roughly $7 million per month, that puts the total closer to $70 million distributed by the end of 2027.

Who Actually Gets This Money, and How Is It Split?

The MLC distributes the unmatched royalties on a pro rata basis, calculated from actual usage data supplied by each streaming service for its U.S. catalog, not from estimates of global market share. Publishers with larger catalogs and higher streaming volumes will take home more. Publishers with smaller footprints take home less. Independent songwriters who are not signed to a publisher receive a share based on their own registered catalog activity through the MLC.

As a point of reference, Billboard's Publishers' Quarterly data from Q2 2026 shows the current landscape: Sony Music Publishing leads the Hot 100 publisher market share at 37.32 percent, a record high. Warner Chappell sits at 17.67 percent, UMPG at 12.45 percent, and Kobalt at 9.38 percent. Those numbers are not the exact formula the MLC uses, but they give you a sense of how lopsided the distribution will likely be toward the majors.

One detail worth flagging: publishers are not required to pass any of this money down to their songwriters. The MMA mandates the distribution to copyright owners, and in many cases the copyright owner is the publisher, not the writer. That gap is one of the central criticisms of the system.

What Independent Songwriters and Small Publishers Should Know

The bigger and more unresolved story sits alongside this distribution. The MLC is still sitting on a separate pool of $397 million in what it calls "historical unclaimed royalties," money that accumulated between 2007 and 2020 before the MLC even existed. Of that, the organization has matched $317 million and distributed $239 million, but roughly $158 million remains unresolved. No firm timeline has been announced for distributing the remainder.

For independent creators, the takeaway is practical: the best thing you can do is make sure your works are fully registered with the MLC and that your metadata is complete and accurate. The more claims the MLC can match before April distributions begin, the more money flows to its actual rightful owners rather than into the market share formula that disproportionately rewards the largest publishers.

If you are an independent publisher or songwriter and you are not sure whether your catalog is registered, the MLC's portal allows direct registration. For creators navigating this without a label or admin deal, resources like [/submit](/submit) and [/pass-the-aux](/pass-the-aux) can connect you with people who understand the publishing side.

The broader argument over whether this distribution model is fair will continue. Critics say it entrenches the advantage of major publishers. Defenders say it is the most workable solution to a nearly impossible matching problem. What both sides agree on: getting this money moving again, after years of stagnation, is better than letting it sit indefinitely. For the independent songwriter community, the window to claim what is rightfully yours before it gets absorbed into market share math is narrowing.
