Sony and Universal Music Group have filed another lawsuit against AI music generator Suno. The labels claim Suno’s recently released v6 model infringes on their copyrights. This new legal action, first reported by The Verge, adds to the legal challenges facing companies that create music with artificial intelligence.

The labels’ complaint states Suno’s v6 model was trained on user outputs from previous models. Those earlier models, Sony and UMG claim, were themselves trained on music ripped from YouTube and other sources without proper licensing. The labels argue this lineage perpetuates copyright infringement, even if v6’s direct training data comes from user-generated content. Sony and UMG have not signed licensing deals with AI companies. This has led to repeated lawsuits against Suno.

This is not Suno’s first data dispute. Our outlet covered Suno’s Studio 2.0 launch on August 14, 2026, noting ongoing discussions about AI music use. Instrument maker D’Addario had publicly acknowledged its own use of AI in music production then. Studio 2.0 introduced MIDI capabilities, expanding user interaction with the AI. But the training data legality issue has not resolved since that release. The current lawsuit shows the labels view Suno’s development, from earlier models to v6, as a continuous chain of infringement.

Legal pressure on Suno reveals a central conflict in the AI music industry. It is the clash between creating commercially viable, “push-button, get-song” tools and protecting the established rights of music creators and publishers. Suno’s ambition to generate compositions ready for top-40 radio directly pits it against an entrenched industry built on copyright protection.

Other AI music players explore different applications. Music startup Thoughtful Things, for example, just launched a Kickstarter campaign for its first instrument, Engram. As The Verge reported, Engram is a sampler and groovebox. It mangles incoming audio using AI and can hallucinate new sounds. Thoughtful Things stresses Engram is not “Suno in a box,” and not a “push-button, get-song” device for radio-ready tracks. This positions Engram as a creative tool for experimentation, not a direct competitor in commercial song generation. By focusing on “broken AI hallucinations” and audio manipulation, Engram aims to avoid the direct copyright infringement claims that affect models trained on existing commercial music.

Repeated legal challenges from major labels like Sony and Universal Music Group will shape Suno’s future and the broader AI music sector. Some companies explore AI for sonic exploration and manipulation. Suno’s path, however, remains defined by its battles over training methodology legality. The labels’ consistent legal action against Suno confirms they will pursue companies whose models use unlicensed content, no matter how many iterations or intermediate user outputs those models incorporate.

What are Sony and Universal Music Group suing Suno over?

Sony and Universal Music Group claim Suno’s v6 model infringes on their copyrights because it was trained on user outputs from previous models, which were themselves trained on unlicensed music from sources like YouTube.

What is Engram?

Engram is a sampler and groovebox from Thoughtful Things that uses AI to mangle audio and generate new sounds, designed as a creative instrument rather than a “push-button, get-song” device.

When did Suno launch Studio 2.0?

Suno launched Studio 2.0 on August 14, 2026, adding MIDI capabilities and drawing attention to broader discussions around AI music use.
