The American Federation of Musicians has sued Universal Music Group and Warner Music Group, claiming the two companies licensed recordings made by its members to AI music firms Suno and Udio without paying or crediting the musicians who played on them.
The lawsuit was filed on Friday (June 5) in the US District Court for the Southern District of New York.
It centers on the settlements and licensing deals that UMG and WMG struck with the two AI music generators, which the union says triggered the “new use” provision of its collective bargaining agreement, according to the complaint, which you can read here.
That provision, the AFM contends, requires the major labels to compensate its members when their recorded work is put to a new commercial use.
“The AFM brings this lawsuit because defendants, two of the largest music companies in the world, have licensed sound recordings on which AFM-represented musicians have worked, without compensation or credit, to two AI companies,” reads the complaint.
“At the same time, they have refused to provide information to the AFM about which recordings and whose work is being licensed.”

American Federation of Musicians’ complaint
The union is represented by attorney Eyad Asad of Cohen, Weiss and Simon, and is seeking unspecified monetary damages alongside an order requiring the labels to disclose which recordings were fed into the AI training sets.
Both majors settled their copyright lawsuits against Udio at the end of 2025 — and WMG also settled with Suno — agreeing to license their catalogs for new AI models the companies plan to launch this year.
The AFM argues that those deals generated money for the labels but not for the session musicians whose performances were used.
“While the Defendants protected their own interests and created a significant source of new revenue with the retrospective settlements and prospective licenses, they have refused to compensate the musicians whose work – created with their own instruments and through their talent, creativity, and hard work – is fed into AI machines for profit,” the AFM said in the complaint.
The union says the labels are “allowing those same AI companies to use the work of AFM-represented musicians to do exactly what they warned about: Training AI models to generate supposedly ‘new’ sound recordings derived from music ingested into their models.”

American Federation of Musicians’ complaint
According to the complaint, UMG and WMG “licensed substantial portions of their music catalogs to the AI companies to train their models on both a retroactive and prospective basis, and will earn further revenue on an ongoing basis from the AI companies.”
“Defendants have failed to share in the settlement proceeds and future revenue with those same artists whose music was copied, used for training, and incorporated into the development of the AI models and platforms now being commercially exploited as a new use of the performances embodied in those recordings, despite their self-congratulatory claims of protecting those same artists,” the AFM said.
The three major record companies – UMG, WMG and Sony Music – first sued Suno and Udio in 2024, in a case coordinated by the RIAA that alleged “mass infringement” of copyright.
Universal Music Group settled with Udio in late October 2025, announcing a compensatory settlement plus license agreements for a new AI music platform set to launch in 2026.
Warner Music Group reached its own settlement and licensing deal with Udio in mid-November 2025.
Days later, WMG became the first major label to settle with Suno, in a deal that also saw the AI company acquire concert-discovery platform Songkick from Warner.
The question of how artists would be paid has followed the Suno and Udio deals since they were announced.
The day after UMG‘s Udio settlement, the nonprofit Music Artists Coalition publicly questioned what share of the revenue would reach artists and how their consent would work.
“The AFM chose this route during our collective bargaining negotiations, and we will continue to work to resolve any issues through these negotiations, as we have in the past. We expect to continue our strong working relationship with the AFM built on mutual respect for the talented musicians in our industry.”

In response to the AFM suit, a UMG spokesperson told MBW in a statement: “Universal Music Group has been at the forefront of protecting the rights and advancing the interests of artists and songwriters in the age of AI—striking responsible AI licensing agreements to ensure they are compensated, leading the charge for legislation to further protect them and taking legal action against bad actors.”

Separately, Warner Music Group told Billboard: “Warner Music Group is growing the value of music by establishing guardrails and architecting a healthy AI ecosystem on the behalf of artists everywhere. We are disappointed by the AFM’s unproductive action amid our ongoing negotiations. We look forward to resuming our negotiations as scheduled.”

Sony Music Entertainment, the third of the major record companies, is not named in the AFM complaint and has not settled with either Suno or Udio.
The lawsuit was filed two days after Suno announced a USD $400 million funding round that valued the AI company at $5.4 billion.Music Business Worldwide
