How Music Licensing Works
How production music pays composers through sync fees and performance royalties, how it differs from royalty-free stock, and what libraries expect.
In 2025 about 106,000 new tracks reached the streaming services every day, up from 99,000 in 2024, according to Luminate’s 2025 Year-End Music Report. The same report found that 88% of the 253 million tracks in its data had 1,000 streams or fewer in the whole year (Hypebot has a summary). Releasing music is no longer the hard part. Getting paid for it is.
Licensing is a different road. Here the music is not the product the listener chooses: it is written to sit under pictures, in a documentary, a reality show, a promo, an advert. A large part of my work is production music, written for publishers and libraries that place it on television. That music has aired through library placements for years, and it is the reason I take the mechanics seriously. You cannot build anything in this business if you don’t know where the money actually comes from.
Two businesses that look the same
Production music and royalty-free stock music look the same from the outside: a big catalogue, a search box, a licence. They are two different business models.
Production music is published. A library, which is a music publisher, signs your track, registers it, pitches it to editors, music supervisors and broadcasters, and licenses it. You earn twice: a share of the fee the client pays to use the track, and your share of the performance royalties every time the programme is broadcast, here and abroad, for as long as it keeps airing.
Royalty-free music is sold as a product. The client pays once, or pays a subscription, and owes nothing further for the uses the licence covers. That is all “royalty-free” means: no further fees for the person who licensed the track. It does not automatically mean the music can never earn performance royalties. AudioJungle, for example, accepts tracks registered with a performing rights organisation, and Pond5 explains how cue sheets work for them. But many royalty-free and subscription catalogues are deliberately free of collecting-society registration, because that is what their customers are paying for.
Where the money comes from
Three streams matter for a composer writing production music.
The sync fee. When a client puts your track in a programme or an advert, they pay to synchronise it with picture. The library negotiates the fee, or covers the use with a blanket licence: an annual or per-series deal that lets a production company or broadcaster use the whole catalogue. The library then shares the income with you according to your contract. Half is a common split, but contracts vary, and under a blanket deal there may be no per-use fee to split at all.
In some countries this part is handled collectively. In the UK, broadcasters and production companies license production music through blanket agreements with MCPS and PRS for Music, so the money reaches writers and publishers as royalties rather than as individual fees.
Performance royalties. When the programme airs, the broadcaster pays its collecting society under a blanket licence: GEMA in Germany, PRS for Music in the UK, ASCAP, BMI and others in the United States. The society shares that money between the works that were used, and it knows which works were used from the cue sheet: the document listing every piece of music in a programme, with titles, writers, publishers and durations. BMI’s guide is a clear introduction. No cue sheet, or a wrong one, and the money goes nowhere.
The royalty is divided into a writer’s share and a publisher’s share. In the US the two are typically split evenly and paid separately: the publisher never touches your writer’s share. PRS for Music guarantees the writer at least 50% of the royalty (registration policy). GEMA works with its own distribution keys, so check its current rules rather than assuming the American split. Wherever you are, you must be a member of a society and your works must be registered correctly, otherwise you collect nothing.
Foreign income. A track placed on one channel can end up in programmes sold to dozens of countries. Collecting societies exchange money through reciprocal agreements, and good libraries have sub-publishers abroad. It is slow money, sometimes arriving a year or more after the broadcast, but it adds up.
Put side by side:
| At a glance | Production music (library or publisher) | Royalty-free stock music |
|---|---|---|
| How the client pays | A sync licence per use, or a blanket licence for the catalogue | A one-off licence fee or a subscription, with no further fees |
| Performance royalties | Yes, through collecting societies, from cue sheets, every time it airs | Only if the track is registered and the use is reported; many catalogues are deliberately unregistered |
| Who finds the client | The publisher pitches to editors, supervisors and broadcasters | Mostly self-service search on a website |
| What the composer earns | A share of sync fees plus the writer’s share of royalties, often for years | A share of each sale or download, or a single upfront fee |
| Typical client | Broadcasters, production companies, agencies | Independent creators, small productions, social video, though big brands use them too |
The deal you sign
Not all libraries work the same way, and the contract matters more than the logo.
Exclusive libraries take the track and you cannot place it anywhere else. In return they invest in it: they register it, deliver it to broadcasters, pitch it, chase cue sheets. Non-exclusive libraries let you place the same track elsewhere. Some do it by retitling, registering your piece under a new name so it can sit in several catalogues at once. That creates duplicate registrations with the societies and conflicts on YouTube, where Content ID does not accept material licensed non-exclusively. It is one reason many libraries insist on exclusivity.
Buyouts pay you a fixed fee upfront and the company keeps the rights. Sometimes that means the publisher’s share; sometimes it means everything. Epidemic Sound is the best-known example: it pays a fixed fee per commissioned track, becomes the sole owner of the financial rights, splits streaming revenue 50/50 with the artist, and only works with artists who are not affiliated with a collecting society (artist FAQ). Music Business Worldwide explains the model in detail. A buyout can be a fair deal for a track with a short life. It is a bad deal for a track that would have aired for ten years.
- Exclusive or non-exclusive, and for how long. Is there a reversion clause if the track is never placed?
- How sync fees are split, and whether an administration fee comes off first.
- Whether your writer's share stays yours and is paid to you by your own society.
- Whether it is a buyout, and of what: the publisher's share, the master, everything.
- Which territories, and who collects abroad.
- Who files cue sheets and registers the works.
- What the contract says about AI training on your music.
Why the relationship matters
Uploading to a stock site is easy: a file, some tags, done. You are now technically “in sync licensing”. In practice you are one anonymous name among millions of files. Nobody knows who you are, nobody calls you, nobody pitches your music for a specific brief.
That is the part I care about most. With a publisher there is a person on the other end. They tell me what editors are asking for, what is missing from the catalogue, which track nearly landed and why it didn’t. When I produced Feel Good – Vocal Pop for Flipper Music, the brief was precise: ten vocal tracks plus instrumentals, house groove with a pop feel, nothing under 110 BPM, no intro or outro longer than thirty seconds, positive lyrics. That kind of brief only exists when someone knows the market and trusts you to deliver. I want to work with people who fight for my music, and I fight for theirs.
There is also a cost to the low end of the market, and I’ll say it plainly. When subscription catalogues present themselves as “music libraries”, clients who don’t know the industry stop seeing the difference between a published production track and a cheap stock file. The pressure on prices is real, and it falls on composers who write for a living.
What libraries ask for
Production music is a volume business. One track rarely changes anything. A catalogue of well-made, well-tagged tracks, placed with the right publishers, starts to work on its own over time: placements bring more placements. These are the things that, in my experience, decide whether a track gets used.
Sound quality first. A track that doesn’t sound finished will not be licensed, however good the writing. If you can’t record or mix to a professional standard, pay someone who can.
Range. Build a catalogue across styles. Some clients want fine dining, others want pizza, and you cannot predict which of your tracks will be the one that works. Often it is the one you thought of as filler.
Shelf life. Trend-driven production can get a lot of use for a few years and then fade. Acoustic instruments, orchestral writing and classic jazz age much more slowly. A healthy catalogue has both.
Structure. Get to the point. No long intros. A track that moves through clear sections gives an editor more to cut from: one programme uses the opening, another the climax. For trailers, a three-part build is close to a requirement.
Function. Ask whether the track has to drive the edit or support it. Under dialogue and voice-over, a busy lead line is a problem. Trailers and promos need the opposite.
Mood. The briefs I see most often ask for uplifting, positive music, and for dark, driving, tense music. Very introspective or very niche music has a market, but a narrow one. Irregular metres and long, complex forms are hard to edit to picture.
Lyrics. When a brief asks for vocals, it usually asks for themes that work under many stories: togetherness, family, friendship, resilience. Specific love-song lyrics are harder to place.
Then deliver versions. A library will usually want:
- Full mix, the main version.
- Underscore, without the lead melody, solos or anything that fights with dialogue. Reality and factual editors live on these.
- Alternate mixes with different emphasis or instrumentation.
- Stems, so an editor can start sparse under dialogue and bring in the full arrangement when the scene needs it.
- Short edits if the library asks for them, for promos and adverts.
Doing the homework
Supervisors and editors search catalogues by words, so metadata is part of the music: genre, mood, instruments, tempo, key, a description that says what the track is for. Libraries work from what you give them: the more precise it is, the more often the track comes up.
Know the programmes you are writing for. IMDb tells you who worked on a series. Tunefind lists the music used in specific shows, episode by episode, which is the fastest way to understand the sound of a programme before you write for it.
A job, not a lottery
Licensing is a job, and it asks for a specific mix of skills: a wide musical vocabulary, an understanding of how music works under picture, professional production and mixing, the ability to turn a vague brief around on a deadline, and enough business sense to read a contract. None of it is glamorous. All of it pays, slowly, if you understand how the money moves.
