A single stream on Spotify or Apple Music typically creates two separate composition royalties: a mechanical royalty for the reproduction of your song, and a performance royalty for the public play of it. They’re collected by different organizations, on different schedules, and missing either one means leaving money on the table.
Here’s the immediate action: affiliate as a writer with a Performing Rights Organization (ASCAP, BMI, SESAC, or GMR), register your compositions with The Mechanical Licensing Collective, and if you own masters, sign up with SoundExchange too.
Every interactive stream generates both a mechanical and a performance royalty, and collecting both requires separate registration with a PRO, the MLC, and SoundExchange where applicable.
| Point | Details |
|---|---|
| Two royalties per stream | Mechanical and performance royalties both trigger on interactive streams but pay through separate systems. |
| Register with the MLC | Streaming mechanicals go unclaimed without an MLC account listing accurate splits and ISWCs. |
| PRO affiliation is separate | Join one PRO as a writer to collect performance royalties on top of any MLC mechanicals. |
| Metadata drives matching | Missing ISWCs, ISRCs, or splits are the leading cause of unmatched royalty pools. |
| Master income needs SoundExchange | Featured artists and rights holders on recordings should register separately for digital performance royalties. |
For artists building a catalog from scratch, sourcing beats with transparent licensing terms from the outset makes tracking splits and metadata far simpler down the line, especially when paired with SoundBridge virtual collaboration tools designed for modern remote workflows. Browse licensed instrumentals built for exactly that kind of clean paper trail, and pair them with proper registration so every stream counts toward both royalty checks.
A mechanical royalty is payment for reproducing a musical composition, whether that’s pressing vinyl, cutting a CD, selling a permanent download, or generating a copy through an interactive stream. The right traces back to compulsory licensing under U.S. copyright law, and its rate for many uses is set through a formal rate-setting process rather than free negotiation.
The MLC has administered the blanket digital mechanical license since January 2021, matching streaming activity to registered works and paying out mechanicals for U.S. streams. Physical mechanicals still often route through direct publisher deals or an administrator like Harry Fox Agency. The Copyright Royalty Board’s Phonorecords IV proceeding governs the statutory and formula-based rates running through the current rate period, and that ruling directly shapes what a mechanical royalty is worth on a given stream.
A performance royalty is owed whenever your composition is played publicly, and “publicly” covers more ground than most songwriters assume. Radio airplay counts. So does a bar playing your track over house speakers, a TV show licensing it for a scene, and a streaming platform serving it on demand.
Performing Rights Organizations (ASCAP, BMI, SESAC, and GMR in the U.S.) license these public uses and distribute the proceeds using a standard 50/50 writer and publisher split. That’s the composition side. The recording itself generates a separate stream of income: SoundExchange collects digital performance royalties on the master and pays them to featured artists and labels, not to songwriters as such. If you wrote the song and performed it, you’re owed money from both a PRO and SoundExchange, through two entirely different pipelines.
Registration is where most creators either capture their full income or quietly forfeit it. The process breaks into three distinct signups, each covering a different royalty.
Publishers and administrators can handle much of this for a percentage, which is worth considering if your catalog has grown past a handful of releases.
Pro Tip: Keep a single spreadsheet with every release’s ISRC, ISWC, composer splits, and publisher IPI numbers. You’ll need it every time you upload to a platform or register a new work with the MLC, and it saves hours when a mismatch shows up later.
The legal answer is straightforward: an interactive stream both reproduces your composition (mechanical right) and publicly performs it (performance right) under the Copyright Act, so it triggers both royalties simultaneously. They’re paid through separate collectors, on separate timelines, which is exactly why so many songwriters end up collecting only one.
Phonorecords IV sets an all-in headline percentage of revenue that platforms pay toward publishing, and the mechanical portion is derived from that formula rather than a flat per-stream fee. Rough industry estimates put performance royalties around $0.0008 to $0.0012 per stream and mechanicals around $0.001 to $0.002 per stream, meaning combined composition income often lands near $0.002 to $0.003 per stream.
| Royalty Type | Collected By | Approximate Per-Stream Range |
|---|---|---|
| Mechanical | MLC (digital), publishers/HFA (physical) | $0.001–$0.002 |
| Performance (composition) | ASCAP, BMI, SESAC, GMR | $0.0008–$0.0012 |

These ranges shift by platform, subscription tier, and total market activity in a given period, so treat them as a planning baseline rather than a guarantee.
Most lost income traces back to a handful of preventable errors. Signing only with a PRO and skipping MLC registration is the single biggest one, since it leaves streaming mechanicals completely unclaimed. Bad metadata runs a close second: a missing ISWC, an unlisted co-writer, or a misspelled name is enough to keep a match from happening.
Unmatched funds accumulate when works can’t be matched to a rights holder, and that pool only shrinks when creators actively claim what belongs to them. Run a quick metadata audit on past releases, correct what’s wrong, and file MLC claims for anything unmatched.
Pro Tip: If a catalog has grown too large to audit by hand, this is exactly the point where a publisher or rights administrator earns their commission.
Pro Tip: Set a recurring monthly calendar reminder to check MLC and PRO statements. Catching a mismatch within a few months is far easier than untangling it two years later.
Thomas here. Working with independent artists building beat packs, the confusion between publishing income and master income comes up constantly. Producers assume a distributor check means they’re covered, when composition royalties often sit unclaimed. Registering your metadata properly, right down to splits and ISWCs, is what turns a matched stream into a matched payment. Make it part of every release, not an afterthought.
What’s the simplest way to explain mechanical vs performance royalties?
Mechanical royalties pay for reproducing a song; performance royalties pay for playing it publicly. A stream typically does both at once.
Do I need to register with both a PRO and the MLC?
Yes. A PRO collects your performance royalties, while the MLC collects your streaming mechanicals. Skipping either one means forfeiting that half of your composition income.
Who collects royalties if I own the master recording?
SoundExchange handles digital performance royalties for masters, paying featured artists and rights holders separately from any PRO or MLC payment.
Why do mechanical and performance royalties arrive on different schedules?
They’re processed by entirely different organizations using different accounting systems, so payment timing rarely lines up even when both come from the same stream.

What causes royalties to go unclaimed?
Missing MLC registration, incomplete metadata like missing ISWCs, and assuming a distributor payment covers composition income are the most common causes.
