Demystifying Streaming Mechanical Royalties and The MLC
How to sign up with the Mechanical Licensing Collective to collect hidden digital mechanical royalties worldwide.
Whenever a song is streamed interactively on platforms like Spotify, Apple Music, or Amazon Music, it generates two distinct publishing royalties for the underlying composition: a Public Performance Royalty and a Mechanical Royalty. While Performance Rights Organizations (PROs like ASCAP and BMI) track and collect performance revenue, they do not touch mechanicals. Millions of dollars in “black box” streaming mechanical royalties sit unclaimed because independent songwriters fail to register with the Mechanical Licensing Collective (The MLC).
Phase 1: Understanding the Music Modernization Act & The MLC
Passed by Congress in 2018, the Music Modernization Act (MMA) fundamentally changed how digital audio mechanics are licensed. Prior to the MMA, streaming services had to send individual Notice of Intent (NOI) documents to every single copyright holder—an administrative impossibility that led to widespread unpaid royalties.
The MMA established a non-profit entity called the Mechanical Licensing Collective to solve this structural breakdown. The MLC administers a single, blanket compulsory license to digital service providers (DSPs), collects the master mechanical streaming pools, matches the audio data against its global song database, and pays out 100% of the statutory mechanics directly to self-published writers, administrators, and publishers.
Phase 2: Verifying Your Collective Infrastructure
A common point of confusion is assuming your digital distributor or PRO automatically routes these mechanicals to you. Review this checklist to confirm your collection gaps:
- Standard Distributors (DistroKid, TuneCore): These platforms deliver audio to DSPs and collect 100% of your Master Recording royalties. Unless you pay extra for a specific “Publishing Administration” add-on tier, they leave composition mechanicals completely uncollected.
- PROs (ASCAP, BMI, SESAC): These organizations track public performance spaces (festivals, broadcast television, radio, and streaming venue profiles). They are legally prohibited from collecting mechanical royalties.
- The MLC: Handles the digital interactive mechanical slice exclusively. Joining is completely free, and by federal mandate, the agency takes a 0% administrative fee from your royalties because its operational costs are funded entirely by the DSPs.
Phase 3: The Step-by-Step MLC Portal Onboarding Process
To establish your direct collection pipe and claim your historic share of streaming mechanical data, you must officially clear the MLC database registration steps:
Mandatory Member Onboarding Steps:
- Determine Member Type: Register as an Individual Writer/Publisher if you are a self-published songwriter who writes melodies/lyrics and does not have a third-party administration deal.
- Tax Setup: Complete your tax profile. The system requires an active W-9 form for US domestic creators or a W-8BEN for foreign creators before any back-royalties can clear processing.
- Claim via The Portal: Once your profile is approved, log into the User Dashboard and use the “Public Work Search” or “Bulk Claiming Tool” to connect your legal identity to existing master audio strings matching your catalog.

Phase 4: Comparative Asset Matching Mechanics
The MLC cannot accurately pay you unless it can cross-reference your composition metadata with the sound recording files distributed to DSPs. Review the mandatory codes required to tie your publishing to the master files:
| Data Asset Element | Acronym | Code Format Target | Primary Purpose |
|---|---|---|---|
| International Standard Musical Work Code | ISWC | T-123.456.789-C | Identifies the unique abstract composition (lyrics/music). Generated by your PRO or publisher. |
| International Standard Recording Code | ISRC | US-AB1-23-45678 | Identifies the specific sound recording asset. Embedded in your audio file by your digital distributor. |
| Interested Parties Information Number | IPI | 9-Digit Numeric String | Ties the unique legal name of a songwriter or publisher to global rights clearing systems. Issued by your PRO. |
Phase 5: Resolving Overlaps and Split Discrepancies
Because multiple creators often share a single track’s ownership, the MLC utilizes an open dashboard interface to flag structural registration conflicts. If two publishers submit split data that collectively exceeds 100%, the MLC implements a strict holding policy.
When a split overlap occurs, the MLC places the contested portion of the song’s mechanical royalty stream into a secure holding escrow account. The parties involved have exactly 90 days to resolve the indexing error, sign updated split sheets, or file formal legal mediation before the system permanently implements default statutory preservation rules.
