AI music is no longer only a copyright fight between record labels and technology companies. It is now becoming a labor fight inside the music business itself.

The American Federation of Musicians of the United States and Canada has sued Universal Music Group and Warner Music Group in federal court in Manhattan. The union says the labels licensed recordings featuring AFM-covered musicians to AI music companies Suno and Udio without paying, crediting or properly informing the players whose performances were part of those recordings.

The lawsuit was filed on June 5, 2026, in the U.S. District Court for the Southern District of New York. The court has not ruled on the claims, and Universal and Warner are expected to contest the union's position.

Why the lawsuit matters

At the heart of the case is a simple but important question: when a record label licenses old recordings for use by a generative AI music system, is that a new commercial use of the musicians' performances?

The AFM says yes. The union argues that its Sound Recording Labor Agreement requires signatory labels to notify the union and compensate musicians when recordings are used in ways that were not covered by the original recording deal.

That matters because many recordings were made long before anyone imagined an AI system that could train on catalog music and generate new songs. A session player may have recorded a drum part, guitar line, string section or horn arrangement for a record, CD, download or stream. The AFM is arguing that using that same performance as part of an AI licensing business is different enough to require new payments and disclosure.

Suno and Udio are not defendants in the AFM case. The union is suing Universal and Warner, the labels that reached licensing or settlement agreements with those AI companies after earlier copyright lawsuits.

How the dispute reached this point

In 2024, major record companies including Universal, Warner and Sony sued Suno and Udio, accusing the AI music firms of training on copyrighted recordings without permission. Those cases were framed mainly as copyright disputes between rights holders and AI developers.

By late 2025, the fight began to shift. Universal announced a settlement and licensing arrangement with Udio in October 2025. The company said the agreement covered recorded music and publishing, would create new revenue opportunities for UMG artists and songwriters, and would support a licensed AI music service launching in 2026.

Warner announced its own agreement with Udio in November 2025. It said the deal resolved copyright litigation and created a framework for a licensed AI music creation service trained on authorized music. Days later, Warner also announced a partnership with Suno, saying the companies would build licensed AI music experiences while giving participating artists and songwriters control over whether and how their names, images, likenesses, voices and compositions are used.

Those announcements were meant to show that the major labels were moving AI music toward permission-based licensing. The AFM lawsuit asks what happens to the musicians who played on the recordings being licensed.

What the union is asking for

The union says Universal and Warner created or will create revenue from AI licensing deals, but did not share that money with AFM-represented musicians. It also says the labels failed to provide enough information about which recordings were licensed, which musicians appeared on them, and when the recordings were transferred or licensed for AI use.

That disclosure piece is important. Without a record-by-record accounting, musicians may not know whether a performance they contributed to has become part of an AI training or licensing arrangement.

The AFM is seeking monetary damages and information about the recordings involved. Music Business Worldwide reported that the union also wants disclosure of which recordings were used in AI training sets.

The labels have rejected the idea that the lawsuit is the right path. Universal said it has worked to protect artists and songwriters through responsible AI licensing, legislation and legal action, and said the union chose litigation during ongoing collective bargaining. Warner said it was disappointed by the action and expected talks to continue.

Why this goes beyond one court case

The lawsuit arrives as AI-generated music is growing quickly. Deezer said in April 2026 that it was receiving nearly 75,000 AI-generated tracks per day, representing about 44 percent of daily uploads to the platform. Deezer also said those tracks still represented only a small share of listening, about 1 to 3 percent of streams.

Suno, meanwhile, announced on June 3, 2026, that it had raised more than $400 million in Series D funding at a $5.4 billion post-money valuation. The company said it planned to begin rolling out its first music model developed in partnership with the music industry in the coming months.

That scale explains why this case is being watched closely. If AI music becomes a major business, the question of who gets paid will become harder to avoid.

Record labels may control many sound recording copyrights, but recordings also contain the work of session musicians, backing performers, arrangers, producers and other contributors. Some of those people are covered by union agreements. Others rely on private contracts or one-time payments. The AFM case is a test of whether existing labor contracts can reach into AI licensing even when those contracts were written before today's generative tools existed.

For the labels, a ruling or settlement that requires payments to union musicians could make AI deals more complex. Companies may need to identify every recording used, match it to contract-covered players, calculate compensation and build reporting systems. That could slow licensing, but it could also make AI music deals more transparent.

For musicians, the case is about more than one payment stream. It is about whether new technology can turn older creative work into fresh revenue without the people behind that work being included.

The bigger question

Universal and Warner say their AI partnerships are designed to build licensed, controlled systems where artists and songwriters can be paid. The AFM is asking whether that promise should also extend to the less visible musicians whose performances helped make the recordings valuable.

That makes the lawsuit more than another AI copyright dispute. It is a test of whether the music industry can build an AI business without repeating an old pattern: new formats creating new money first, and fair participation for working musicians arriving later, if at all.
