The MMA and the MLC Explained

The Music Modernization Act (MMA) changed how certain U.S. digital mechanical royalties are licensed and paid. Its most important publishing-related change was a blanket mechanical license for eligible digital music providers, such as services offering covered interactive streams and certain downloads. The Mechanical Licensing Collective (The MLC) administers that license: digital service providers send usage data and royalties to The MLC, The MLC matches those uses to musical works, calculates amounts, and distributes payments to registered rightsholders.

That system matters because a stream or download involves more than the sound recording you hear. It also involves the underlying musical work—the composition, including its music and lyrics. The MLC’s Title I role concerns mechanical royalties for eligible U.S. digital audio uses. It does not make The MLC the collector for every type of music income. Performance royalties, sound-recording or master royalties, international royalties, noninteractive webcasting uses, and other excluded activities follow different rules or systems.

The MMA is therefore best understood as a U.S. licensing and administration framework, not as a universal royalty system for every territory, platform, or revenue category.

What the Music Modernization Act changed

Congress enacted the MMA in 2018, and it was signed into U.S. law on October 11, 2018. The law was designed to modernize parts of the music-licensing system as listening moved toward digital services and large-scale usage reporting. The U.S. Copyright Office describes the statute as having three separate titles, each with a different subject. The Creation of the Music Modernization Act confirms the law’s signing date and modernization purpose, while The Music Modernization Act summarizes its structure.

Title I addresses musical-work licensing modernization. This is the title most relevant to songwriters, music publishers, publishing administrators, and eligible digital music providers. It created the statutory blanket mechanical license for covered digital phonorecord activities, including interactive streams and certain downloads. The blanket structure gives an eligible provider a centralized way to obtain coverage for qualifying uses instead of relying on a separate work-by-work license for every use.

Title II concerns pre-1972 sound recordings. That subject is separate from the Title I mechanical-license system for musical works. Title III concerns the allocation of certain royalties to producers, mixers, and sound engineers. Because the three titles address different problems, explaining the MMA only as “the streaming royalty law” leaves out important scope and can blur together musical-work royalties and sound-recording royalties.

Title I also established The MLC as the designated nonprofit administrator for the blanket license. The Copyright Office’s Music Modernization: FAQ describes The MLC’s role in receiving digital service-provider notices and reports, collecting and distributing royalties, identifying works and owners, and maintaining a public database. The law made the blanket license available beginning January 1, 2021, subject to the statute’s conditions, exclusions, and implementation rules. The Music Modernization Act provides the Copyright Office’s overview of that timing and structure.

What a mechanical royalty is in this context

A mechanical royalty is connected to the reproduction and distribution of a musical work. In the digital context covered by Title I, the relevant use may be an eligible interactive stream or certain download activity. The royalty belongs to the musical-work side of the transaction, which can include songwriters, publishers, and administrators depending on the work’s ownership and representation.

This is distinct from the sound recording, sometimes called the master. The same listening event can involve multiple rights and payment streams. The MLC’s Title I administration concerns the eligible U.S. digital mechanical royalty for the musical work. It does not replace organizations or agreements handling performance royalties, master-side royalties, or foreign royalties.

That distinction is practical. If a songwriter sees income from a digital service, the payment may not all come from one organization, and an absence of a payment from The MLC does not by itself prove that every royalty category is missing. The first question should be: which right, territory, use, and licensing system does the payment concern?

The route from a digital use to a payment

The basic workflow can be shown as a three-part route:

DSP usage reports and royalties → The MLC matching, calculation, and distribution → rightsholder registration, share claims, and payments

For a covered use, the digital music provider submits usage information and the corresponding royalties to The MLC. The usage information is intended to identify what was used, when, and under the provider’s reporting obligations. The MLC then uses its database and matching processes to connect the reported use to the correct musical work and ownership information. After the use is matched, The MLC calculates the amount owed under the applicable statutory rate and distributes royalties to the rightsholders who are positioned to receive them. Home / How It Works explains this operational sequence, and the statutory data, reporting, payment, and licensing provisions appear in 17 U.S. Code § 115 — Compulsory license for making and distributing phonorecords.

A simplified example helps. Suppose an eligible U.S. interactive streaming service reports that it used a recording associated with a particular composition. The provider sends the relevant usage record and royalty payment to The MLC. The MLC searches its work information and recording metadata, attempts to match the use to the composition, checks the ownership shares, calculates the applicable amount, and directs the resulting payment to the registered parties whose shares are established.

If the composition has one songwriter and one publisher with clearly documented shares, the administrative path may be relatively straightforward. If the song has several writers, multiple publishers, an administrator, conflicting claims, incomplete data, or no registration, the payment may require additional research or remain unmatched or held until the ownership issue is resolved. The example illustrates the process; it does not establish a universal per-stream amount.

Why registration and matching matter

Registration is not merely a profile-building exercise. It gives The MLC the work, writer, publisher, share, and contact information needed to associate reported uses with the people and companies entitled to payment. Songwriters, publishers, and administrators should register relevant works and maintain that information so they are positioned to receive eligible U.S. digital mechanical royalties.

The MLC’s How to register works with The MLC instructs users to search before creating a new registration and to provide work, writer, publisher, and ownership-share information. It also describes optional recording metadata that can improve automated matching. Searching first matters because duplicate or conflicting registrations can make the database harder to interpret.

A practical registration checklist is:

• Search The MLC’s database before adding a work.
• Confirm the composition title and writer information.
• Enter publisher or administrator information where applicable.
• Record ownership shares accurately and make sure the shares are internally consistent.
• Add available recording information when it can help connect a usage report to the composition.
• Keep contact and ownership information current.
• Review possible conflicts or unmatched uses rather than assuming a missing payment is a platform error.

Registration does not replace a contract, chain-of-title documentation, tax form, or other legal or administrative requirement. It also does not collect royalty categories outside The MLC’s Title I role. It is one part of making ownership information discoverable and usable within this particular U.S. system.

Why a payment can be delayed or incomplete

The MLC’s matching process depends on the quality and completeness of the information available. Payment can be delayed or incomplete when a work is unregistered, a share is unclaimed, ownership data conflicts, a usage cannot be matched confidently, or a royalty is affected by a dispute or legal hold. Music Modernization: FAQ describes The MLC’s identification and distribution responsibilities, while How to register works with The MLC explains the information used for registration and matching.

These problems are not all the same. An unregistered work creates a discovery problem: The MLC may have usage data but lack a clear record of who owns the composition. A conflicting share creates an ownership problem: multiple records may claim the same interest or the reported percentages may not reconcile. An unmatched use creates an identification problem: the service’s usage information may not connect cleanly to a registered work. A dispute or hold creates a payment-control problem: even if a use has been identified, funds may not be distributable until the issue is addressed.

The useful response is to compare the service’s usage information, the composition’s registration, the ownership agreement, and any publisher or administrator records. Keep a clear record of titles, alternate titles, writer names, identifiers, shares, and recordings. When a discrepancy appears, resolve the underlying data rather than submitting multiple speculative registrations.

Who sets the rates?

The MLC administers the license and distributes royalties, but it does not set the statutory mechanical royalty rates. The Copyright Royalty Judges (CRJs) establish statutory rates and terms through the applicable rate-setting process. Section 115 assigns rate-setting and related statutory functions within that framework. The Copyright Royalty Board’s Phonorecords IV announcement states that the Phonorecords IV rates apply from January 1, 2023 through December 31, 2027 and describes configuration-specific digital formulas, including headline percentages in the 15.1%–15.35% range for specified calculations.

There is no single universal “per-stream rate” that can be safely applied to every service or use. Rates can vary by configuration, rate period, and the applicable formula. The MMA changed the rate-setting standard, but it did not itself establish a universal annual Consumer Price Index formula for interactive-streaming rates. Applicable regulations and CRB proceedings determine the relevant terms and calculations.

For that reason, a practical explanation should avoid promising that every stream pays a fixed amount or that rates automatically increase according to one simple annual formula. A payment question should identify the specific use, service, rate configuration, and period before anyone tries to calculate what was owed.

Oversight, audits, and rulemaking

The MMA includes oversight mechanisms. The MLC has statutory audit rights concerning DSP payments, and musical-work copyright owners have statutory audit rights concerning royalty payments by The MLC. The Copyright Office administers the related filing and notice process. Music Modernization Audits confirms both audit pathways and the Copyright Office’s role in the process.

The Copyright Office also administers related rulemakings and public notices addressing implementation topics such as DSP notices, reports, payments, the public works database, transparency, designation review, termination-related distributions, and late fees. Its Music Modernization Act Rulemakings and Ex Parte Communications page lists those implementation subjects.

Audit rights do not mean every payment discrepancy should immediately become an audit. They are formal statutory tools with eligibility, timing, notice, and procedural requirements. Anyone considering one should review the current statute and regulations and obtain appropriate professional advice for their circumstances.

What this means for music professionals

For a songwriter, the central lesson is data hygiene. Register compositions, document ownership shares, keep writer and publisher information current, and connect recordings to works where the available metadata supports matching.

For a publisher or administrator, the job includes maintaining accurate catalogs, reconciling shares, addressing conflicts, monitoring unmatched activity, and making sure registrations reflect the agreements and ownership records you actually rely on.

For a digital music provider, the system creates reporting, payment, notice, and data responsibilities under the blanket-license framework. The MLC is the administrator receiving those reports and payments, not the entity that decides the statutory rate.

For anyone investigating a missing payment, begin by narrowing the question: Is this an eligible U.S. digital mechanical royalty? Is the composition registered? Are the shares complete and uncontested? Does the usage record contain enough information to match the recording to the work? Is the money subject to an unresolved claim, dispute, or hold? Those questions usually produce a more useful diagnosis than asking generally whether “streaming royalties” were paid.

The MMA and The MLC therefore solve a specific administrative problem. The law created a centralized blanket-license structure for eligible U.S. digital musical-work uses, and The MLC operates the data-and-payment process behind it. The system can work only as well as the reports, registrations, ownership claims, and matching information that feed it. Accurate records do not guarantee a particular payment, but they put the rightsholder in a much stronger position to be identified, matched, and paid.
