Sony Music Files Another Lawsuit Against Udio, Alleges AI Music Generator Copied 30,000 Songs to Train Models

Sony Music Entertainment has launched a fresh legal offensive against the AI music startup Udio, accusing the company of unlawfully incorporating more than 30,000 tracks into its artificial intelligence training systems. The songs in question span a wide roster of artists, including Beyoncé, Harry Styles, and Elvis Presley. The complaint, filed Monday with the U.S. District Court for the Southern District of New York, expands upon earlier litigation from June 2024, when Sony, Universal Music Group, and Warner Music Group jointly targeted both Udio and its rival Suno. During the discovery phase, investigators pinpointed 30,117 specific recordings embedded in Udio’s datasets—a revelation that prompted Sony to take further legal action. However, U.S. District Judge Alvin K. Hellerstein, a jurist known for overseeing complex intellectual property cases in New York, rejected Sony’s initial bid to incorporate these newly identified tracks into the original lawsuit. This decision forced the label to file a separate claim to safeguard its copyright protections. Judge Hellerstein’s ruling underscored that the fresh evidence warranted a distinct legal proceeding, a move that legal analysts say highlights the intricate challenges of managing large-scale copyright disputes in the age of artificial intelligence. Notably, Udio, founded in 2023 by former Google researchers, has marketed itself as a platform to democratize music creation, yet its methods have sparked fierce debate over artist compensation. Dr. Elena Torres, an intellectual property expert, remarks: “This case isn’t just about one catalog—it’s a pivotal moment for determining whether AI can operate within a framework that respects creative ownership.”

Sony’s complaint asserts that “fundamental principles of copyright law require that reproducing protected sound recordings for commercial AI development, like Udio’s platform, demands explicit permission from rights holders.” The label warns that without such safeguards, “AI services risk devaluing the artistic works that serve as essential raw materials for their operation,” and that unregulated offerings “could replace, rather than enhance, genuine human creativity.” Sony is seeking at least $150,000 in damages for each allegedly infringed work, along with a court injunction to bar Udio from using its catalog for model training. In its defense, Udio has previously argued that training on copyrighted songs uploaded to YouTube constitutes fair use, describing the process as “a behind-the-scenes technical operation, invisible to the public, aimed at producing an ultimately non-infringing new product.” Representatives for Sony and Udio did not immediately respond to requests for comment. This legal battle unfolds against a backdrop of heightened scrutiny over AI’s use of copyrighted material, with critics pointing to Udio’s reliance on YouTube-sourced data as particularly contentious given the platform’s intricate copyright rules. Since the initial lawsuits, both Universal Music Group and Warner Music Group have settled with Udio through licensing agreements, with the startup now preparing an industry-backed model for release later this year. Sony, however, continues litigation with Suno alongside Universal, arguing that these settlements prove Udio could have legitimately licensed its tracks rather than allegedly scraping them from YouTube.

“At its core, this case is about ensuring that copyright continues to incentivize human invention and imagination, as it has for centuries,” Sony states in its filing. “Achieving this goal doesn’t require stifling technological progress, but it does demand that Udio comply with copyright law and honor the creators whose works enable its functionality.” Legal experts suggest the outcome could establish a precedent for how AI firms access copyrighted data, potentially reshaping the landscape for generative music tools. The dispute echoes historical clashes, such as the Napster litigation of the early 2000s, which redefined digital music distribution, hinting at the transformative impact this ruling could have on AI’s role in creative fields. As the music industry grapples with these challenges, the case represents a broader test of whether generative AI can coexist with traditional copyright frameworks. Industry observers note that Sony’s stance reflects a growing push among rights holders to assert control over their catalogs in an era of rapid technological change. The label contends that licensing agreements, rather than unauthorized scraping, offer a viable path forward for AI development, a position that could influence future negotiations between tech startups and creative industries. Ultimately, this legal battle may serve as a benchmark for balancing innovation with the protection of intellectual property in the digital age.
