Understanding Music Royalties – Composition, Publishing, and Mechanical Royalties


Standard Disclaimer: This is intended to be a helpful guide to a high level overview of the big concepts in music publishing and how royalties work. (Because the question comes up a lot). However. there’s a lot of nuance and grey areas in all this, so if you’re getting into serious record deals or scenarios where large amounts of money are involved, do yourself a huge favour and retain an experienced music industry lawyer to help navigate these processes.


During a collaboration between artists and producers, ownership and royalty splits should come up early — if everyone’s excited and hoping for success, it should. Nobody wants to be caught undocumented on a hit.

That said: hits are rare, and getting uptight about splits on a track that may only see modest interest isn’t a good use of energy. Cover the bases with a simple agreement. That’s enough to protect the upside and prevent future conflict.

Copyrights – Publishing & Master

There are two separate copyrights in almost every song.

1. The song / composition
This is the underlying writing: lyrics, melody, chords, harmony, song structure.
This is the publishing side.

2. The sound recording / master
This is the actual recorded track that gets released to Spotify, Apple Music, etc.
This is the master side.

That distinction matters because different revenue streams pay different people. Working on a song does not necessarily mean a collaborator participates in both publishing and master depending on their contribution. The differentiator is whether or not they are involved in the actual songwriting process contributing melodies or composition to the work.

In a lot of small indie projects, these lines get blurry — everyone may end up working on everything to some degree.This is the part to be negotiated and make sure everyone is comfortable with the credit and role(s) attributed to them on the project.

Producers vs. Co-Writers

A producer can be:

Just a record producer
They help shape sounds, arrangement, performance, recording, mixing direction, etc. That alone does not always make them a songwriter.

Or:

A co-writer/composer
If they created chords, topline melodies, musical hooks, basslines, harmony, or core musical ideas in the song, they usually are contributing to the composition.

It’s important to have open communication and agree upon the roles that everyone will be credited with (and ultimately paid for if royalties are collected).

Royalty Streams

Publishing / Composition Money

Performance royalties
Paid when the composition is publicly performed: radio, TV, live venues, streaming, etc. In the U.S., PROs like ASCAP or BMI collect performance royalties for songwriters and publishers. SOCAN handles performance royalties in Canada and, since acquiring SODRAC in 2018, also administers reproduction/mechanical rights. CMRRA is another major Canadian mechanical licensing administrator. ASCAP also notes that performance royalties are split 50% writer share / 50% publisher share

Mechanical royalties
Paid when the composition is reproduced, which today mostly means streams, downloads, and other reproductions of the song. In the U.S., The MLC collects eligible digital audio mechanical royalties from services like Spotify and Apple Music and pays songwriters, composers, lyricists, publishers, and administrators. The MLC notes these streaming mechanicals are not a simple fixed per-stream amount; they depend on service revenue, subscriber counts, sound recording payouts, and performance royalties. 

Mechanical royalties from The MLC are small per stream, so meaningful income generally requires either a hit-level release or a catalog deep enough that aggregated streams add up. For most indie releases, MLC revenue is modest — but registering your compositions is still essential, because unregistered works collect nothing, and unclaimed royalties do accumulate.

Synchronization income
Paid when the composition is licensed into film, TV, ads, games, etc. ASCAP notes that sync fees are paid to the publisher and then shared with the songwriter according to contract. Synchronization rights are often treated separately from a basic agreement. These arrangements are usually unique agreements with the licensor and depend a lot on the intended use for the music and are not a one-size-fits-all arrangement the way that performance royalties and mechanical royalties are treated. Contributors will likely need to sign off separately on sync agreements, and establishing who must sign off up front is a really good idea to avoid missing opportunities later.

Master / Sound Recording Money

Master streaming/download revenue
The money paid for use of the actual recording, usually flowing to whoever owns the master, often a label or the independent artist/producer team via a distributor. This is separate from publishing/mechanical income. This separation is reflected in The MLC’s explanation that mechanical royalties are calculated in part alongside amounts paid to sound recording owners. Mechanicals from physical sales and non-blanket sources are collected separately (e.g., via HFA or direct licenses).

Digital performance royalties for the master
In the U.S., SoundExchange collects for certain non-interactive digital uses like Pandora radio-style streams and SiriusXM. SoundExchange says these are paid 45% to featured artists, 50% to the sound recording copyright owner, and 5% to non-featured artists’ fund(s).

Best practice

Before release, put in writing:

  • who owns the composition
  • who owns the master
  • exact percentage splits
  • who administers publishing
  • who registers the song with the PRO / CMO
  • who collects master income from the distributor
  • whether the producer also gets any separate producer royalty or fee from the master

The checklist above covers what to write into your collaboration agreement. But getting paid also depends on making sure the right organizations know your song exists in the first place — which is a separate set of registrations nobody does for you automatically.

Who You Actually Have to Register With

One of the most common — and expensive — misconceptions in indie music is that signing up with a distributor like DistroKid and joining a PRO like ASCAP or SOCAN covers you for everything. It doesn’t. Each royalty stream flows through a different system, and each system requires its own registration. Miss one, and that money either sits unclaimed or goes to someone else.

Here’s the practical breakdown for a US/Canadian indie release in 2026.

What your distributor covers

Your distributor (DistroKid, TuneCore, CD Baby, AWAL, etc.) handles the master side only by default. They:

  • Deliver your recording to Spotify, Apple Music, YouTube Music, Tidal, Amazon, etc.
  • Collect the master/sound-recording royalties from those DSPs
  • Pay you (minus their cut or subscription fee)

That’s it. A plain distribution account does not collect mechanicals, does not collect performance royalties, and does not register your composition anywhere. Your distributor knows about the recording, not the song underneath it.

What your PRO covers

Your PRO (ASCAP, BMI, or SESAC in the US; SOCAN in Canada) handles performance royalties on the composition. They:

  • Collect the writer’s share and publisher’s share of performance royalties from radio, TV, live venues, and interactive streaming
  • Pay out globally through reciprocal agreements with foreign PROs (SOCAN ↔ ASCAP, PRS, GEMA, JASRAC, etc.)

Critical catch: if you only register as a writer and don’t have a publisher set up, you typically only collect the writer’s share (50%) and leave the publisher’s share (the other 50%) on the table. You can set up your own publishing entity with your PRO to claim both sides, but you have to actually do it — it isn’t automatic.

What nobody collects unless you specifically sign up for it

This is where indie artists lose real money:

Mechanical royalties from US streaming. The MLC is the only body collecting blanket-license digital mechanicals in the US, but you have to register as a self-administered songwriter (or be covered by a publishing administrator that registers on your behalf). Your PRO doesn’t do this. Your distributor doesn’t do this by default. If you never register with The MLC and don’t have a publishing admin, your US streaming mechanicals sit in the unclaimed pool.

Mechanical royalties internationally. Outside the US, mechanicals are collected by a patchwork of societies — MCPS in the UK, GEMA in Germany, SACEM in France, JASRAC in Japan, and so on. No single registration covers all of them. This is the gap that publishing administrators (Songtrust, CD Baby Pro, TuneCore Publishing, DistroKid Publishing, Kobalt) are built to fill: they register your compositions with global societies and collect from all of them for a percentage cut (typically 15–20%).

Neighboring rights on the master (non-US digital performance). In the US, SoundExchange collects digital performance royalties for the master from non-interactive services like SiriusXM and Pandora. You have to register directly with SoundExchange — your distributor doesn’t do this. Outside the US, neighboring rights societies (Re:Sound in Canada, PPL in the UK, SoundExchange-equivalent bodies in most countries) collect for both digital and terrestrial radio use of the master. Re:Sound, in particular, is worth knowing about for Canadian artists — it’s a real revenue stream for Canadian radio play that you only collect if you register.

YouTube Content ID. Separate system again. Most distributors offer Content ID registration as an add-on (often with a revenue cut). Without it, UGC videos using your music generate nothing for you.

Sync licensing. Not a registration at all — a direct negotiation. Neither your PRO nor The MLC nor your distributor will place your music in a film, game, or ad. Sync happens through publishers, sync agents, music libraries, or direct relationships.

The practical minimum stack for a US-based indie writer/artist

Here’s what actually covers the bases for a typical indie release:

  1. A distributor (DistroKid, etc.) — master streaming/download income
  2. A PRO (ASCAP, BMI, or SESAC) — performance royalties, writer and publisher share; register yourself as both
  3. The MLC — US blanket-license mechanicals (free to register as a self-administered writer)
  4. SoundExchange — US digital performance on the master (free to register)
  5. A publishing administrator (Songtrust, DistroKid Publishing, CD Baby Pro, TuneCore Publishing) — international mechanicals and publisher-share collection worldwide; optional if you’re willing to do per-society registration yourself, but realistically indispensable for most indie writers

The practical minimum stack for a Canadian indie writer/artist

Here’s what actually covers the bases for a typical Canadian indie release where you write, perform, and own your masters:

  1. A distributor (DistroKid, TuneCore, CD Baby, etc.) — master streaming/download income
  2. SOCAN — performance royalties worldwide, writer and publisher share; register as both if self-published (free for writers, $50 one-time for publisher)
  3. SOCAN RR (opt-in after joining SOCAN) or CMRRA — Canadian mechanical/reproduction royalties; pick one, not both
  4. The MLC — US blanket-license mechanicals (free to register as a self-administered writer)
  5. MROC or ACTRA RACS (Artisti in Quebec) — performer’s share of Canadian neighboring rights via Re:Sound
  6. Connect Music Licensing (Panorama in Quebec) — master owner’s share of Canadian neighboring rights via Re:Sound
  7. SoundExchange — US digital performance on the master; your Canadian performer collective (MROC/ACTRA RACS/Artisti) can often collect this via reciprocal agreement, but direct registration is also free and worth doing.
  8. A publishing administrator (Songtrust, DistroKid Publishing, CD Baby Pro, TuneCore Publishing) — international mechanicals and publisher-share collection outside Canada and the US

The Canadian stack has more moving parts than the US one, mostly because neighboring rights are split between separate performer and master-owner collectives. The upside: those royalties are meaningful in Canada because terrestrial radio is in scope, unlike the US.

Don’t skip ISRC codes. Every recording needs one embedded in its metadata — it’s how Re:Sound and the other Canadian collectives match broadcast and streaming reports to your tracks. Connect Music Licensing issues them free. Miss this step and your royalties still accrue, but the collectives can’t identify them as yours.

One thing to know about publishing administrators

A publishing administrator is not a publisher in the traditional sense — you keep ownership of your copyrights. They’re a service that registers your songs globally and collects on your behalf for a percentage. The tradeoff is the cut (usually 15–20% of collected royalties) versus the time and expertise required to register with 60+ societies yourself.

For most indie writers, the math favors using an administrator. For writers with enough catalog volume or international reach to justify the staff time, direct registration can make sense.

What nobody will do for you

One last note: copyright registration (with the US Copyright Office or Canadian Intellectual Property Office) is separate from everything above. Your PRO, The MLC, your distributor, and your publishing admin all deal with royalty collection, not copyright protection.

Copyright registration is separate from royalty collection. In the U.S., registration is generally required before suing for infringement of a U.S. work. In Canada, registration is optional but can be valuable evidence if you ever need to enforce your rights.
