The most common question I get from indie artists goes something like: "If I wrote the song and I recorded the song and I distribute the song myself, why is there a separate royalty I'm supposed to be collecting?"
The answer is that copyright law treats "writing a song" and "recording a song" as two different acts that create two different copyrights. Even if the same person did both of them, the law separates them. And because the law separates them, the money flows through different pipes.
If you release your own music and you're not paying attention to the mechanical royalty pipe specifically, you are leaving money on the table. It's not a huge amount of money for most artists. But it's real, and it accumulates, and it's yours.
The two copyrights, very briefly
Every recorded song has two copyrights. The composition is the underlying work — melody, harmony, lyrics. The sound recording is the specific performance captured on a master. If a cover band records your song, the composition is still yours; they own the sound recording of their version.
The composition side generates three kinds of royalty: performance royalties (when the song is publicly performed — radio, streaming, live venues — collected by PROs), mechanical royalties (when a copy of the song is made, reproduced, or distributed — originally vinyl and CDs, now primarily digital streams and downloads), and sync royalties (when the song is placed in visual media — covered separately in the sync guide).
What a mechanical royalty actually is
Historically, mechanical royalties came from physical reproduction — a label pressing 10,000 CDs paid the songwriter a statutory rate for each copy made. In the streaming era, the category has expanded. Every time a track streams on a service that counts as "interactive" (Spotify, Apple Music, Amazon Music), a small mechanical royalty is generated on the composition side, separate from the master royalty that flows to whoever owns the recording.
In the US, mechanicals from streaming are collected by the Mechanical Licensing Collective (MLC), which was created by the 2018 Music Modernization Act specifically to solve the problem of unpaid digital mechanicals. The MLC is the reason I keep telling songwriter-producers: if you haven't registered with the MLC, you have unclaimed royalties sitting in an account.
Outside the US, mechanicals are collected by country-specific mechanical societies — GEMA in Germany, MCPS in the UK, and so on — and typically administered through your publishing administrator or publisher.
Why the self-releasing artist problem exists
The whole system was built on the assumption that the songwriter and the recording artist were different people. When you're both, the money still gets split into two buckets; it's just that both buckets belong to you. The master bucket goes through your distributor. The composition bucket — mechanicals and performances — goes through your PRO and your publishing administrator (or the MLC directly, in the US).
If you don't have a publishing administrator and you haven't registered with the MLC, the master side of your money flows normally through your distributor, but the mechanical composition side piles up in an account with no owner. Eventually that money gets redistributed back into the industry pool via the MLC's "black box" distribution, which means it goes to other people.
What to actually do
- Register with your PRO — ASCAP, BMI, SESAC, or whichever is right for you. This handles the performance side of the composition.
- Register with the MLC — directly, if you're US-based and self-publishing. This handles the US mechanical side.
- Get a publishing administrator — SongTrust, Kobalt, CD Baby Pro, or similar. This handles international mechanicals and makes sure your metadata is clean across every territory where your music is played. The administrator takes a percentage (usually 10-20%) in exchange for running the paperwork. For most indie artists the math works out strongly positive — you collect more with an administrator than without, net of their fee.
- Use a split sheet for every co-write. The mechanical pipeline assumes the splits on each composition are accurately registered. Mismatched or undocumented splits are the most common reason artists don't get paid on songs they co-wrote.
The bigger picture
Mechanical royalties are a small line item on a single release and a non-trivial line item over a career. They also interact with neighboring rights, sync licensing, and international performance royalties in ways that make your whole rights-administration setup more valuable than the sum of the parts.
If you're only watching the master royalty line, you're watching maybe 70% of the money a release is capable of generating. The other 30% is on the composition side, and for self-publishing artists, every dollar of it is yours — if you set up the paperwork.
