Sony and UMG are suing Suno again
Sony and UMG sue Suno again, claiming its new AI music model still uses stolen copyrighted songs.

Why Now
The lawsuit follows Suno’s release of its v6 model, which the labels say was trained on user outputs from earlier infringing models.
What Happened
Sony and UMG allege Suno’s v6 model was trained on user data that includes copyrighted music ripped from YouTube and other sources. They accuse Suno of “model laundering,” arguing that training a new model on outputs of an infringing model does not eliminate infringement. Suno said v6 was trained from the ground up with a new data set, but did not detail the sources.
Why It Matters
If the court sides with Sony/UMG, it could force AI music companies to clean their training data or face legal liability, reshaping how generative music models are built. It also signals that copyright holders are actively policing AI training pipelines.
The Limitation
The outcome is uncertain; the lawsuit is still pending and details about Suno’s data sources remain undisclosed.
What You Can Do
Review your own AI music projects to ensure training data is properly licensed or cleared.
