Music Licensing Glossary — Sync, Master, Publishing, and Royalty Terms

A track for which all necessary rights — both master and publishing — have been confirmed, documented, and (usually) licensed prior to use. Supervisors filter aggressively for cleared tracks because uncleared rights can stop a placement at legal review. A cleared track delivered with a complete metadata sheet and split sheet is the gold standard.

The underlying song — melody, harmony, lyrics — as distinct from any specific recording of it. Owned by the songwriter(s) at the moment of creation. The composition copyright (also called the publishing) generates performance, mechanical, sync, and print royalties. A single composition can have many separate masters (e.g., the original recording, a cover, a live version) each owned independently.

The document broadcasters and producers file with PROs to trigger performance royalty payments. Lists each piece of music used in a program by cue, duration, type of usage (background instrumental, visual vocal, theme), writers and publishers, their ownership shares, and PRO affiliations. Without an accurate cue sheet your placement may air without you ever earning the performance royalty. Writers don’t usually file cue sheets themselves — the broadcaster does — but you must supply correct metadata so they can fill it.

Music composed specifically for a particular project on commission. Usually structured as work-for-hire, meaning the producer or studio owns both master and publishing in the resulting cues. Common in film, TV, advertising, and games where the production wants original music tailored to picture rather than pre-existing tracks.

A library that holds the only rights to license a given track. The writer cannot place that track elsewhere — not with another library, not direct to a supervisor, not on a sync portal — for the duration of the term. Exclusive libraries typically pay better and have stronger supervisor relationships than non-exclusive libraries, but the cost is loss of control over the track.

A short-term sync license limited to film festival exhibition. Typically issued at a discounted fee or no fee with the understanding that broader rights (theatrical, streaming, broadcast) will be negotiated separately if the film is acquired or distributed. Filmmakers use festival-only licenses to keep early-stage costs down; if the film sells, they upgrade to full sync.

Music and sound design produced for video games. Game placements involve different licensing conventions from film and TV: in-game cues are often work-for-hire, while licensed songs in cutscenes follow standard sync structures. Performance royalties are limited because games are interactive rather than broadcast, but high-profile titles increasingly trigger PRO payments through territorial regulations.

International Standard Recording Code. A unique 12-character identifier for a specific master recording (e.g., USABC2400123). Required for digital distribution, streaming, and SoundExchange. Every recording you release should have one. Distributors generate them automatically; you can also register your own through the US ISRC agency at usisrc.org.

International Standard Musical Work Code. The composition equivalent of ISRC; a unique identifier for a song (the underlying work, not any specific recording). Issued by ASCAP, BMI, SESAC, or SOCAN when you register a composition. Required for clean cue sheet processing and proper royalty allocation across territories.

A curated collection of pre-cleared tracks made available to music supervisors, editors, and ad agencies for licensing. Catalogs range from boutique exclusive libraries (a few hundred tracks) to massive non-exclusive libraries (tens of thousands). Each catalog has a sonic identity, a price tier, and a set of relationships with supervisors that determine which tracks actually get pitched. See the library representation guide for working strategy.

A submission of a track to a library or supervisor either in response to a brief or as a general catalog inclusion. A good pitch includes a one-line vibe summary, three to five reference artists, a clean WAV, an instrumental, properly named stems, full metadata, and confirmation of one-stop or co-write status.

The specific recording of a composition, separate from the underlying song. The master copyright is owned by whoever paid for the session and signed the producer/engineer agreements — typically the artist if self-released, the label if signed. Generates streaming royalties, master use fees in sync, and digital performance royalties via SoundExchange.

A license granted by the master recording owner permitting use of a specific recording in audiovisual content. One half of the standard sync clearance (the other half being the sync license for the underlying composition). On a typical $20,000 sync deal, the master fee and the sync fee are usually paid 50/50 unless a different split is negotiated.

A royalty paid for reproducing and distributing a recording of a composition. In the streaming era, mechanicals on US streams are collected by the MLC and paid to publishers and self-administered songwriters. Physical mechanicals (CDs, vinyl) are licensed directly or through HFA. Statutory mechanical rate in the US is currently 12.4% of streaming service revenue allocated to publishers, with adjustments per the Phonorecords IV / V settlements.

A clause stating that one party will receive terms at least as favorable as those given to any other party in the same context. In sync deals, MFN is most often invoked between master and publishing to keep their fees aligned. If the publisher accepts $10,000 and the master owner has MFN, the master owner is automatically guaranteed at least $10,000.

The US entity created by the Music Modernization Act (2018) to administer streaming mechanical royalties. The MLC collects from streaming services and distributes to publishers and self-administered songwriters who have registered their works. Songwriters who do not register lose access to their share.

The professional responsible for selecting, licensing, and clearing music for a film, TV show, ad, game, or trailer. Supervisors maintain relationships with libraries, publishers, labels, and independent artists. The most influential supervisors in film and TV (Alexandra Patsavas, Mary Ramos, Liza Richardson, Susan Jacobs, Maggie Phillips, Robin Urdang and others) effectively curate the placement market in their genres.

The duration and scope of a sync license, including media (TV, theatrical, digital, all-media), territory (US, North America, worldwide), exclusivity, and term length (one year, three years, in perpetuity). Each axis affects the price. A typical mid-budget TV sync runs all media, all territories, in perpetuity, for the life of the program.

The cash royalty income flowing to the rights holder annually after administrative deductions. The standard input to catalog valuation: catalog value equals annual NPS times a multiple (typically 8x-16x for stable catalogs). See how much is my music worth for the full method.

A library where the same track can be licensed by multiple libraries simultaneously, often through retitling. Non-exclusive libraries are accessible to more writers and pay smaller fees per placement, but offer the volume play of being in many catalogs at once. Common entry point for new writers; mature writers usually move toward exclusive deals.

A track where a single party controls 100% of both the master and the publishing, allowing licensing with one signature, one phone call, one wire transfer. Supervisors love one-stops because they remove clearance friction on tight deadlines. Mark every deliverable as one-stop where applicable; it is a competitive advantage.

A royalty paid for the public performance of a composition — on radio, TV, streaming services, in restaurants and venues, at concerts, in fitness studios. Collected by ASCAP, BMI, SESAC, or GMR in the US and the equivalents in other territories (PRS in the UK, GEMA in Germany, SOCAN in Canada, etc.). Often the largest and longest-tailed income stream for a successful song.

An organization that collects performance royalties on behalf of songwriters and publishers. The four US PROs are ASCAP (member-owned), BMI (now for-profit since 2024), SESAC (invitation-only, for-profit), and GMR (Global Music Rights, invitation-only). Every working songwriter must affiliate with exactly one PRO; you cannot dual-affiliate. Choice depends on genre, deal-making philosophy, and the personal relationships you can build with each.

Music written specifically for fast licensing in audiovisual production. Often pre-cleared, with simplified rights structures (one-stop, library-controlled), and tagged for searchable use cases (uplifting corporate, dark cinematic, energetic sports, etc.). The bulk of TV background scoring, ad music, and YouTube content uses production music.

The 50% of publishing royalties traditionally allocated to the publisher (with the other 50% going to the songwriter). Self-published songwriters retain 100% of the publisher share. Co-publishing deals split the publisher share between the writer-controlled entity and a major or independent publisher (often 50/50, leaving the writer with 75% of total publishing).

Royalty income generated by the underlying composition copyright. Includes performance (collected by PROs), mechanical (collected by MLC), sync (negotiated case-by-case), and print royalties. Distinct from master recording royalties, which are owned and collected separately.

A practice in non-exclusive libraries where the same underlying track is registered under different titles by different libraries to track which library generated which placement. Legitimate but operationally messy: it complicates PRO registration, can create cue sheet conflicts, and requires careful split-sheet management. Most premier libraries are exclusive and avoid retitling entirely.

A new recording produced to evoke a famous song’s vibe when the original is unavailable, too expensive, or rights-blocked. Common in advertising. Legally distinct from the original (re-recorded with new performance), so only the sync license to the underlying composition is needed — not a master use. Also called a re-record or knockoff.

The US collecting body that distributes digital performance royalties on master recordings — the master’s equivalent of a PRO. Pays artists (45% of royalties), featured artists collectively, and master rights owners (50%) for non-interactive streaming on SiriusXM, Pandora radio, webcasts, and similar services. Free registration at soundexchange.com.

A signed document among co-writers documenting the ownership percentages of a composition. Sign it the day you write the song, before anyone gets paid, before anyone has reason to argue. Templates are free from ASCAP, BMI, and SongTrust. Missing or contradictory split sheets are the single most common reason placements fall through at legal review.

The disassembled instrument and vocal tracks of a song, delivered separately so editors and supervisors can rebalance the mix to picture. Standard set: full mix, instrumental, TV mix (no lead vocal, with backgrounds), a cappella, plus split stems for drums, bass, guitars, keys, lead vocals, background vocals, and FX. See sync delivery specs for full bouncing rules.

A request from a supervisor, agency, or production describing the music needs for a specific scene, spot, or campaign. A typical brief specifies genre, mood, tempo, lyric guidance, era cues, reference tracks, vocal vs instrumental, license type required (one-stop preferred), budget, deadline, and exclusivity terms.

The upfront license fee paid for permission to synchronize a piece of music with audiovisual content. Fees range from $0 (festival-only or unpaid student film) to $1,500-$5,000 (low-budget TV background instrumental), $10,000-$50,000 (network TV vocal placement, mid-tier ad), $100,000+ (national ad campaign vocal), and $500,000-$2M+ (major movie trailer or Super Bowl spot for a famous song).

A license granted by the publisher of the underlying composition to synchronize the song with audiovisual content. Half of the standard sync clearance pair (the other half being the master use license). Negotiated case by case; rates depend on use, media, term, exclusivity, and the placement’s prominence (background, featured, theme).

The 50% of publishing royalties allocated to the songwriter. The songwriter share cannot be assigned away in most US cases (it stays with the writer), although the income stream from it can be sold or pledged. The publisher share is the half that publishers buy or administer in publishing deals.

Music licensed for use in promotional trailers (movie, TV, game, streaming series). Typically a short, high-fee placement: trailer houses pay premium rates because the trailer is a brand-defining marketing asset. Trailer placements often use cinematic instrumental remixes, sound-alikes, or pre-existing trailer cues from specialty houses (Audiomachine, Two Steps from Hell, Position Music, Hi-Finesse).
