Claiming Unclaimed MLC Royalties: Step-by-Step Guide for Songwriters

Millions of dollars in unmatched mechanical streaming royalties are sitting quietly in “black box” accounts right now. If you are a DIY songwriter, producer, or self-published artist pulling in streams on platforms like Spotify and Apple Music, there is a very real chance some of that money belongs to you.

Unlike performance rights organizations like ASCAP, BMI, or SESAC—which collect public performance royalties—The Mechanical Licensing Collective (MLC) handles the digital audio mechanical royalties generated every single time someone streams or downloads your composition in the US.

If you haven’t set up your profile or used the Mechanical Licensing Collective search tool to track down missing funds, your publishing checks might just be sitting there waiting for you.

Why Do Unclaimed Royalties Even Happen?

Every time a track gets streamed, it actually generates two distinct types of royalties:

1. The Sound Recording Royalty: Collected by your distributor (think TuneCore, DistroKid, or CD Baby) and paid out to whoever owns the master.

2. The Composition (Mechanical) Royalty: Collected via blanket licenses by the MLC and paid directly to songwriters and publishers.

The catch? When digital service providers report all those streams to the MLC, the metadata isn’t always clean. Co-writers get left off, ownership splits don’t add up, or independent artists simply aren’t registered in the system yet. When the MLC can’t automatically match a stream to a rightsholder, the money gets dumped into unmatched status.

Heads Up: Unclaimed mechanical royalties don’t sit in limbo forever. Historical unmatched funds eventually get redistributed, making it crucial to hunt down your money sooner rather than later.

Step-by-Step: How to Search the MLC Database & Claim Your Royalties

If you’re self-published and handling your own rights, here is the exact workflow to find and claim your missing cash.

Step 1: Run a Search in the Public Database

You don’t even need to make an account to see if your tracks are floating around in the system.

• Head over to the Public Work Search tool on the MLC website.

• Type in your song titles, writer name, or your IPI/CAE number.

• Take a look at the results to see if your tracks pop up, who is currently listed as the publisher, and whether your ownership split looks accurate.

Step 2: Open Your Free MLC Account

Membership with the MLC is 100% free—they don’t take a single percentage cut of your royalties.

• Go to their portal and sign up for a Member Account.

• Have your legal info, tax docs (W-9 or W-8BEN), and banking info ready so they actually know where to send your payouts.

• Quick note: If you already use a publishing administrator like Songtrust or TuneCore Publishing, check with them first. They usually handle this stuff automatically, and double-registering will just create a headache.

Step 3: Dive Into the MLC Claiming Tool

Once you’re logged into the Member Hub, resist the urge to immediately register every song from scratch. If a co-writer or your distributor already logged a partial version, dropping a fresh entry on top of it will just cause duplicates.

• Open up the Claiming Tool from the menu in your Member Hub.

• Search using your details (song title, writer name, IPI, or ISWC).

• Look for entries where your shares are missing or unassigned.

• Hit View and then Edit to plug in your rightful ownership percentage and hit submit.

Step 4: Register Missing Works and Match Recordings

If your songs genuinely aren’t in the database anywhere, use the Works Registration Tools to add them manually (one by one or via batch upload).

Also, make sure to check the Matching Tool inside your portal. This section surfaces audio recordings (tracked by ISRC codes) that haven’t been successfully tied to a composition yet. Proposing matches here is how you connect incoming streaming data directly to your catalog.

Quick Checklist for Independent Creators

• [ ] Audit your catalog: Run your name and song titles through the MLC Public Search.

• [ ] Claim existing entries: Use the Claiming Tool to attach your name to partially registered tracks instead of making duplicates.

• [ ] Keep your metadata consistent: Make sure your legal name, IPI number, and splits match everywhere—across your PRO, the MLC, and your distributor.

Taking 20 minutes to dig through the MLC database is one of the easiest ways to ensure your hard-earned streaming revenue actually hits your bank account instead of getting lost in the machine.
