KOMCA, the Korea Music Copyright Association (한국음악저작권협회), is the principal performing rights organisation (PRO) in South Korea. It collects performance and mechanical royalties on behalf of songwriters, composers, and publishers whose works are used in South Korea or globally where reciprocal agreements apply.
If you are a songwriter on a K-pop track, your publishing income flows through KOMCA. If you are a global writer whose song gets covered or sampled by a K-pop artist, your income from Korean usage flows through KOMCA back to your home PRO.
What is KOMCA?
KOMCA was founded in 1964 and is the dominant Korean collecting society for musical-work rights (the composition side, not the recording side). It operates under the authority of South Korea’s Copyright Act and is the country’s largest copyright collective by membership and royalty volume.
Its functions are standard PRO functions, adapted to the Korean market:
- License usage: KOMCA grants blanket licenses to broadcasters (television, radio), streaming services (Melon, Genie, FLO, Spotify Korea, Apple Music Korea), live venues, public-performance establishments, and other music users in Korea.
- Collect royalties: from those licensees, on the works in KOMCA’s repertoire.
- Distribute royalties: to the member songwriters, composers, and publishers whose works generated the usage.
- Manage reciprocal agreements: with PROs worldwide (ASCAP, BMI, SESAC, PRS, GEMA, SACEM, JASRAC, MCSC, and dozens more) so Korean writers earn from international usage and international writers earn from Korean usage.
Why does KOMCA matter beyond Korea?
Three reasons.
First, K-pop’s global scale means K-pop publishing income is now a significant global publishing category. A K-pop hit with co-writers in Stockholm, Seoul, and Los Angeles generates royalties that flow through KOMCA in Korea, STIM in Sweden, and ASCAP or BMI in the US, with reciprocal accounting between them.
Second, the Korean streaming market is dominated by domestic services (Melon, Genie, FLO) more than most music markets. Royalties from those services flow to writers via KOMCA. A non-Korean writer whose song is performed by a K-pop act earns from Melon plays through their home PRO’s reciprocal flow with KOMCA, not directly.
Third, KOMCA is the gatekeeper for one of the most distinctive cultural-policy features of the Korean music industry: the “credit system” that lists composers, lyricists, and arrangers on every release. The credit ecosystem and the income flow through KOMCA are tightly coupled.
How does KOMCA work in practice?
Two participation paths:
1. As a Korean songwriter or composer
Korean writers join KOMCA as members and register their works. Every work registration captures the writers, their splits, and the publishing administrator (if any). KOMCA then distributes income from Korean usage to the registered writers proportionally.
2. As a non-Korean writer with K-pop placements
Non-Korean writers do not join KOMCA directly. They join their home PRO (ASCAP, BMI, SESAC, PRS, etc.) and register the work there. When the work is used in Korea, KOMCA collects the Korean usage royalties and transmits them, via the reciprocal agreement, to the writer’s home PRO, which then pays the writer.
This is why so much of the K-pop top-line ends up paid out in Sweden, Norway, the UK, and the US, where many K-pop co-writers are based.
What this means for global indie songwriters
Three working rules.
1. If you co-write with Korean writers, register the work at your home PRO and ensure KOMCA registration matches. Mismatches between your home PRO’s split sheet and KOMCA’s registration are a top source of unpaid Korean royalties. Read splits sheet for the broader context. Your Korean co-writer’s publishing administrator handles the KOMCA filing, but you should confirm the registration matches your home registration.
2. Korea’s streaming income mechanics are different from Western services. Korean DSPs use a different settlement timeline and rate structure than Spotify or Apple Music. The Korean DSP royalty pool flows through KOMCA for the writer’s share. If your home PRO statement shows Korean income arriving 12 to 18 months after the play, the delay is the international flow, not negligence.
3. KOMCA is the song side, not the master side. Performance and mechanical royalties from your composition are KOMCA’s domain. Master royalties (the sound recording) flow through your label or distributor via standard DSP DSR processes. Read master vs publishing for the broader split.
Common KOMCA mistakes and gotchas
- Unregistered split shares. If a K-pop track has five writers but only four are registered with KOMCA, the fifth writer’s Korean income may pool as black-box royalties until the registration is corrected.
- Slow international flow. Royalties from Korean usage to non-Korean writers can take 12 to 24 months to land via reciprocal flow. This is normal but feels slow.
- Romanisation inconsistencies. Korean writer names romanised differently across registrations (Park vs Bak, Lee vs Yi, Choi vs Choe) can create matching failures between KOMCA and home PROs. Use a single romanisation consistently.
- Sample clearance gaps. K-pop tracks that interpolate or sample international works without proper clearance create disputes that play out across KOMCA and the international PRO simultaneously.
- Live-performance income confusion. Korean live venue and concert royalty collection is handled differently from Western counterparts. Tour grosses in Korea generate KOMCA-collected performance income on a separate schedule from your touring agency’s settlement.
- Confusing KOMCA with KFMC. KFMC (Korea Federation of Music Copyright) is a separate organisation focused on different rights and use cases. They are not interchangeable.
KOMCA in the global K-pop context
The K-pop global wave from BTS, BLACKPINK, NewJeans, Stray Kids, and the broader 4th-generation idol scene has pushed KOMCA into international visibility it never had in the Cha Cha era. The Korean Ministry of Culture and the music industry’s collective bodies have invested in upgrading KOMCA’s international reciprocal infrastructure to keep up with the flow.
For independent writers anywhere in the world, the KOMCA flow is no longer an exotic edge case. It is a regular line on global publishing statements for any writer with K-pop placements.
How InterSpace Distribution handles this
InterSpace Distribution focuses on the master-recording side of distribution, where catalog ships via DDEX to Korean DSPs (Melon, Genie, FLO, Bugs, Vibe) alongside global platforms. Writers and publishers receiving income from those releases through KOMCA continue to do so through their home PRO and publishing administrator. Clean splits and accurate writer credit metadata on the master delivery support clean publishing-side registration downstream, reducing the black-box risk on the KOMCA flow.
