Three Los Angeles songwriters filed a federal copyright complaint on Wednesday alleging that BTS's song SWIM copied an unpublished demo they wrote under the same title. Steve Cooper, Jon Sandler and Greylyn Johnson sued HYBE companies, Big Hit Music, Artist Publishing Group and several credited writers in the Central District of California. The filing is a claim, not a finding that anyone copied protected work. [1][2][3]

The useful part of the complaint is not an audio clip. It is the route the plaintiffs say their demo traveled. They allege that they completed it in March 2025 and sent it to music-industry contacts through the sharing platform DISCO. Among those recipients, the complaint says, were representatives of Artist Publishing Group. [1]

The plaintiffs further allege that APG representatives listened to the demo and shared it with others, including Derrick Milano, an APG songwriter credited on BTS's SWIM. Music Business Worldwide reports that the complaint attaches a DISCO listening report as an exhibit. The same complaint says another industry contact received the recording and passed it to writers and producers. None of those allegations has yet been tested in court. [1]

That distinction separates a copyright case from the fandom court assembled beneath comparison clips. Similarity and access answer different questions. Two songs may sound alike without copying. A plausible route to the earlier work may matter, but alleging a route does not prove that a particular writer received, heard or used the demo. The complaint must eventually connect distribution to access and access to protectable expression.

The plaintiffs hired musicologist Alexander Stewart, whose preliminary report, quoted in the complaint, says the songs share a title hook, harmonies, textures and rhythmic and lyrical elements. That is the plaintiffs' expert evidence. It is not a judicial conclusion, and the defendants have not yet supplied the adversarial answer that would let a court compare methods and disputed musical elements. [1][3]

The chronology gives the theory its shape. The plaintiffs say they began circulating the demo in 2025. BTS worked on the album Arirang in Los Angeles that year, according to the complaint. The released album containing SWIM arrived in March 2026. After repeated listening, the plaintiffs engaged Stewart in April and filed suit July 8. Each date is pleaded as part of the claimed chain; a sequence is not itself proof of transmission or copying. [1]

The plaintiffs also say they registered their composition with the U.S. Copyright Office and tried to resolve the dispute before filing. Music Business Worldwide reports that the parties either did not respond or did not reach a resolution, while Radio Facts says representatives had not commented when it published. Registration and attempted contact help establish procedure. Silence does not admit the allegations, and a failed private negotiation does not make the pleaded route more likely to be true. [1][3]

The remedies require the same discipline. The songwriters seek an injunction, damages and a share of profits. Alternatively, they ask for co-writer recognition, royalty participation and an accounting. Those are requests to the court, not awards. No judge has ordered the song removed, assigned credit or found money owed. [1][2]

The named defendants also require care. The case targets corporate entities and credited writers; Radio Facts notes that BTS and its individual members are not themselves named as defendants. [3] Public discussion will still use the group's name because the released song carries it. Legal responsibility, however, follows the complaint's parties and evidence rather than the intensity of attachment to a performer.

This is why the entertainment ledger outranks taste war. Music trades can identify the filing, the alleged access chain, the defendants and the requested remedies. K-pop accounts can compare fragments and argue about resemblance. Neither exercise determines what a court will find. The file still lacks answers from the defendants, tested discovery about who accessed the demo and a ruling on which alleged similarities copyright law protects.

The complaint matters because it converts a fan argument into inspectable claims. DISCO records, recipients, dates and credits can be challenged. The plaintiffs' musicologist can be examined. The defendants can contest access, originality, protectability and similarity. That process is slower than placing two clips side by side, but it is the only route from allegation to finding.

For now, the most accurate verb is allege. The songwriters allege a demo path. They allege copying. They request credit, money and an injunction. The court has found none of those things. A shared demo may become the case's bridge from resemblance to access, or it may fail under scrutiny. Fandom cannot decide which by pressing play.
