Catalog of Music: Your Guide to Getting Paid Right

Your Catalog of Music: Your Guide to Getting Paid Right begins with understanding what you actually own. Your catalog is the collection of copyrights you control (every song you have written, co-written, produced, or hold rights to, including demos sitting on your hard drive). It is an income-generating asset, but only if you register it correctly, maintain clean metadata, and know which royalty streams to collect from. This guide covers the registrations, documentation, and tracking systems that ensure you get paid for every use of your work across all territories and platforms.

What counts as a music catalog and why most writers undervalue theirs

Your catalog is every musical work you have created or acquired rights to. That includes released singles, album tracks, sync placements, and unreleased demos. If you wrote it or co-wrote it, it belongs in your catalog. If you own the master recording, that is a separate but equally valuable catalog asset.

Most independent writers undervalue small catalogs. You do not need 500 songs to generate meaningful income. A catalog of 20 well-registered works earning modest streaming and performance royalties can produce consistent quarterly payments. The mistake is thinking catalog value comes from volume alone. It comes from correct registration, clean metadata, and understanding which royalties each work is eligible to collect.

Unreleased works still have value. A demo you recorded three years ago and never distributed can be registered with your PRO and will generate performance royalties if it ever gets played publicly, synced to a video, or released later. Writers who wait until a song is "successful" to register it leave money on the table during the months or years between release and registration. Register everything.

The two copyrights in every song

Every song contains two distinct copyrights: the composition (the musical work: melody, lyrics, arrangement) and the master recording (the specific recorded performance of that work). These are separate assets that generate separate royalty streams, and you may own one, both, or neither depending on your deals.

By default, the person who writes the song owns the composition copyright. If you co-write, you and your co-writers own it together in agreed shares. The person or entity that pays for the recording session owns the master by default. If you self-release a track you wrote and recorded in your bedroom, you own both copyrights 100%. If you sign a traditional label deal, you typically assign the master to the label while retaining your composition ownership.

This split determines which royalties you can collect. Composition owners collect performance royalties (when the song is played publicly), mechanical royalties (when it is reproduced or streamed), sync fees (when it is licensed to visual media), and print royalties (sheet music). Master owners collect neighboring rights (when the recording is broadcast or played publicly in certain territories), direct licensing fees, and a share of streaming revenue paid to the recording owner.

Building your Catalog of Music: Your Guide to Getting Paid Right through registration

Registration is not optional if you want to be paid. Royalties do not find you automatically. You must register your works with the organizations that collect on your behalf, and each registration unlocks specific royalty streams. Miss a registration and you miss the income it controls.

Mandatory registrations for composition owners: your local PRO (ASCAP, BMI, SESAC in the US; PRS in the UK; GEMA in Germany; SACEM in France; APRA in Australia, etc.), which collects performance royalties. If you are US-based, the MLC, which collects mechanical royalties from US streaming services. If you own masters, SoundExchange (US) or your local neighboring rights organization (PPL in the UK, GVL in Germany, etc.).

Each registration requires specific identifiers: IPI or CAE number (your songwriter/publisher ID), ISRC codes (per recording), ISWC codes (per composition), and accurate writer/publisher splits. Incomplete registrations mean incomplete payments. The MLC will not pay you for a work it cannot match to your account. A PRO cannot distribute performance royalties for a work you never registered.

Registering with your PRO

PRO registration is the first step for any songwriter. In the US, you choose one PRO (ASCAP, BMI, SESAC, or GMR) and cannot be a member of multiple PROs simultaneously. In most other territories, there is one PRO per country and membership is automatic or required to collect.

You will need an IPI number (Interested Party Information), which your PRO assigns when you join. This is your unique identifier across the global royalty system. Every work you register must include the IPI numbers of all writers and publishers, along with their ownership shares. If you co-wrote a song, all co-writers must agree on the split before you register.

Register works as soon as they are finished, not when they are released. PROs can take months to process registrations, and royalties are only paid from the date of registration forward in many cases.

MLC registration for US mechanical royalties

The Mechanical Licensing Collective (MLC) is the US organization that collects mechanical royalties from streaming services like Spotify, Apple Music, and Amazon Music. If you are a US-based songwriter or publisher, registration is free and mandatory if you want to receive these royalties. The MLC does not replace your PRO. It handles mechanicals; your PRO handles performance royalties.

You will need to claim your works in the MLC portal by matching them to the recordings that streaming services report. This requires accurate ISWC codes and ISRC codes. If your metadata is incorrect or incomplete, your works will sit in the MLC's unmatched pool and you will not be paid.

The seven royalty types your catalog should generate

A properly registered catalog generates income from multiple royalty streams. Each stream has different collection mechanisms, payment schedules, and registration requirements.

Performance royalties: paid when your composition is played publicly (radio, TV, live venues, streaming services, bars, restaurants). Collected by your PRO.

Mechanical royalties: paid when your composition is reproduced (CDs, vinyl, downloads) or streamed. Collected by the MLC (US streaming), HFA or MCPS (physical/download), or your local MRO.

Sync royalties: paid when your composition or master is licensed for use in visual media (film, TV, ads, video games, YouTube videos). Requires active licensing deals. Not collected by PROs or MROs; you negotiate these directly or through a publisher/sync agent.

Neighboring rights: paid when your master recording is broadcast or publicly performed in certain territories. Collected by SoundExchange (US) or organizations like PPL (UK), GVL (Germany), SENA (Netherlands).

Micro-sync royalties: paid when your music is used in user-generated content on platforms like YouTube, TikTok, Instagram. Collected through Content ID (YouTube), TikTok's commercial music library deals, or Meta's music licensing agreements.

Direct licensing royalties: paid when you license your music directly to a client (a brand, a filmmaker, a podcast) without going through a PRO or publisher. You negotiate the fee and terms.

How to document ownership and splits before problems start

Split sheets are the only defense against co-writer disputes. A split sheet is a written agreement signed by all writers and producers on a song that documents who owns what percentage of the composition. It should be signed before the song is released, ideally before it leaves the writing session.

Without a split sheet, ownership defaults to equal shares among all writers in most jurisdictions. If three people wrote a song and never documented splits, each owns 33.33%. If one writer believes they contributed 50% and the others disagree, the dispute can freeze royalty payments for years.

Use a standard split sheet template (ASCAP, BMI, and most PROs provide free ones). Include full legal names, IPI numbers if available, PRO affiliations, contact information, and exact percentage shares. All parties sign and date. Keep a copy in your catalog documentation and send copies to all co-writers.

Metadata is how you get paid or do not get paid

Metadata is the information that connects your catalog to royalty payments. Accurate ISRC codes, ISWC codes, IPI numbers, UPC or EAN codes, and writer/publisher credits are what allow PROs, MROs, streaming services, and CMOs to match uses of your music to your account. Incorrect metadata means your royalties go into a black box and are eventually distributed to someone else.

The most common metadata errors: misspelled writer names, missing or incorrect IPI numbers, ISRC codes that do not match between your distributor and your PRO registration, works registered with different titles in different systems, and missing co-writer information. Each error creates a mismatch, and mismatches mean unpaid royalties.

Your distributor (DistroKid, TuneCore, CD Baby, etc.) assigns ISRC codes when you upload a track. Make sure those codes are included in your PRO and MLC registrations. If you register a work with your PRO before you release it, you will not have an ISRC yet. Go back and add it after release.

Audit your metadata annually. Log into your PRO, MLC, and distributor accounts and verify that all information matches. If you find discrepancies, correct them immediately.

When to use a publisher or administrator versus going direct

Publishers take 15% to 50% of your royalties in exchange for global registration, royalty collection, sync pitching, and advance payments. Administrators take 10% to 20% and handle registration and collection but do not pitch your music or provide advances. Going direct means you keep 100% but do all the work yourself.

Use a publisher if you have a catalog large enough to justify their attention (usually 50+ commercially released works), if you do not have time to handle global registrations and CMO memberships, or if you want someone actively pitching your music for sync. Publishers like Kobalt, Songtrust, and Sentric offer global administration with sync pitching at 15% to 25%.

Use an administrator if you want someone to handle the paperwork but you do not need sync pitching or advances. Services like Songtrust (10% to 15%) and Sentric (15%) register your works globally, collect from foreign CMOs, and send you statements.

Go direct if your catalog is small (under 20 works), if you have time to manage registrations and track royalties yourself, or if you are already generating sync income through your own network. You keep 100%, but you are responsible for registering with every PRO, MRO, and CMO in every territory where your music is used.

Tracking what you are owed across territories and platforms

Royalties come from dozens of sources on different schedules. Your PRO distributes quarterly or semi-annually. The MLC distributes monthly. SoundExchange distributes quarterly. Foreign CMOs distribute anywhere from monthly to annually. Streaming services pay your distributor monthly, who then pays you on their own schedule. Sync fees are paid per deal.

Black box royalties are royalties that CMOs and PROs collect but cannot match to a rights holder because of missing or incorrect metadata. These royalties sit in a pool for a set period (usually two to three years), then are distributed pro rata to other members. If your metadata is wrong, your money goes into the black box and you never see it.

Audit your royalty statements every quarter. Compare what you are paid to what you expect based on streaming numbers, radio plays, and live performances. If a song has 500,000 Spotify streams but you received no mechanical royalties from the MLC, your metadata is wrong or your work is not registered. Do not assume the system works. Verify.

Your Catalog of Music: Your Guide to Getting Paid Right is complete when you register everything, document ownership, maintain clean metadata, and track your payments across all sources. The work is administrative, repetitive, and unglamorous. The payoff is every dollar you would otherwise leave on the table.
