Who Actually Writes This: A KOMCA Investigation

Ravi, formerly of VIXX, holds 215 songwriting credits with the Korea Music Copyright Association — more than any other idol in the country. RM of BTS has 187. Woozi of SEVENTEEN has well over 150. These numbers circulate constantly in K-pop fan spaces as proof of a specific narrative: that fourth-generation idols, unlike the manufactured pop stars of decades past, are the true authors of their own music.

The numbers are real. The narrative built on top of them is mostly true, partially exaggerated, and resting on a database that was never designed to answer the question everyone is asking it. This is an audit of that database — what KOMCA actually tracks, what it can’t tell you, and what happens when you pull the credits on specific songs and count, name by name, who is actually in the room.

The Database Everyone Cites and Almost No One Reads Correctly

The Korea Music Copyright Association — KOMCA — is the country’s primary collective rights management organization for musical works, founded in 1964. It is enormous: over 55,000 members, and in 2024 it collected roughly ₩437 billion (about $297 million) in licensing fees, distributing ₩424 billion of that back to rights holders. When a songwriter, composer, or arranger contributes to a track, KOMCA logs it. The database is public. Anyone can search it. This is precisely why it has become K-pop fandom’s favorite forensic tool — a seemingly objective, government-adjacent record of who really made what.

But the database has a structural blind spot, and it’s one that almost never makes it into the listicles ranking idols by credit count.

This single limitation is the reason this entire investigation exists. The headline numbers — Ravi’s 215, RM’s 187, Woozi’s 150-plus — are accurate counts of how many KOMCA-registered works list these men as contributors. They are not, on their own, evidence of how much of any individual song each of them actually wrote. To find that out, you have to stop counting credits and start reading them.

The Credit Leaderboard, and What It Actually Shows

Before dismantling the leaderboard, it’s worth seeing it in full — because the scale of these numbers is genuinely part of the story. Even accounting for the database’s limitations, accumulating 100-plus songwriting credits over a seven-to-ten-year career requires consistent, repeated presence in the writing room. That much is real.

What this list actually demonstrates is something narrower than “these idols write all their own music.” It demonstrates that a specific subset of idols — almost entirely group leaders, almost entirely men, almost entirely from groups built around a designated in-house producer — have sustained, multi-year creative relationships with their group’s music. That’s a real and notable phenomenon. It is also a different claim than the one usually attached to these numbers.

Auditing the Actual Songs

This is where the investigation gets specific. Below are full credit breakdowns — every name KOMCA and official liner notes attach to the writing and composition of three representative title tracks, each one routinely cited as evidence of “self-producing.” Idol names appear in white. Names belonging to outside professional songwriters and producers appear in gold.

The pattern across all three audits is consistent, even though the three groups occupy very different positions in the “self-producing” conversation. Idol involvement is real in every case. Idol involvement is also, in every case, partial — happening inside a structure built, arranged, and in most cases substantially composed by professional outside writers and producers whose names rarely appear in fan-facing marketing.

Three Tiers of “Self-Producing”

Having audited the credits, a clearer taxonomy emerges than the flat “they write their own music” claim that circulates in press coverage. K-pop’s self-producing idols sort into roughly three tiers, and conflating them is most of what makes this topic confusing.

None of these tiers are illegitimate. Tier 2 participation — a member writing real lyrics inside a song built by professional composers — is exactly how a great deal of pop music, across every country and genre, actually gets made. The issue isn’t that K-pop idols collaborate with professional songwriters. The issue is that “collaborates with professional songwriters” and “self-produces” get marketed as synonyms when they describe meaningfully different levels of authorship.

Why the Myth Has Institutional Backing

Part of why the self-producing narrative carries so much weight is that KOMCA itself has a formal, scarce, prestige-coded tier that fans correctly recognize as meaningful — and then over-apply to every writing credit below it.

Full KOMCA membership is genuinely difficult to obtain. It requires three consecutive years as an associate member, royalty income of roughly ₩30 million per year sustained across that period, and approval from KOMCA’s board — and only 25 people across the entire Korean music industry, in any genre, are promoted in a given year. When Woozi reached full membership in 2019, when 3RACHA achieved it as a unit in January 2023, when S.Coups followed in January 2025 — these were real, board-verified, financially substantiated markers of consistent professional songwriting income, not just participation.

The problem is that this genuinely rigorous distinction gets collapsed, in casual fan discourse and in press coverage written for a general audience, into the much looser claim that any idol with any KOMCA credit is operating at the same level. A member with one associate-tier credit on a single album track gets discussed in the same breath as a full member with a decade of consistent royalty income. The database doesn’t make that distinction obvious. Most articles citing the database don’t either.
