Google Hides That It Trained Lyria on YouTube Music

Google is almost certainly using music uploaded to YouTube to train its Lyria music generator — it just doesn't want to admit it in court.

Lawsuit from independent musicians

A group of independent musicians has filed a lawsuit against Google, accusing the company of unlawfully using their songs to train Lyria 3 — an advanced music generator that can create new compositions from text descriptions. According to the plaintiffs, their works, uploaded to YouTube, became part of the training dataset for this AI, without their knowledge or consent.

The lawsuit comes in response to growing concerns in the music industry about how companies train generative AI models. Musicians and record labels have long suspected that their works are used for machine learning without explicit consent — but proving it is difficult. The Lyria case has become the first serious legal proceeding on this issue.

What Google says

Google filed a motion to dismiss the lawsuit, arguing in court documents that musicians themselves granted Google a license to use their content. The company insists that when uploading videos to YouTube, users automatically agree to the service's terms, which give Google (and YouTube) a "broad license" to use uploaded content for any purpose.

"Their claim is based on an unfounded hypothesis that we trained the model on their specific works," Google writes in court documents, relying on the letter of the terms of service rather than on user intent.

By Google's logic, the license you grant the platform extends to anything the platform might create in the future.

License vs. copyright

The key issue in the dispute is how to interpret the license that users grant YouTube when uploading content. The company argues that this license covers all uses, including AI training, even if musicians were unaware of it when uploading.

This creates a paradox for independent creators. When they upload music to YouTube so people can hear it, they are effectively granting the company the right to use that music in ways that may emerge in the future — including training generative models that later compete with their own works.

• Music on YouTube can be used for AI projects without additional creator consent
• Terms of service cover new use cases that users were not aware of
• Musicians have virtually no control over how their works are applied in machine learning
• AI companies cite existing licenses when training new models
• Copyright becomes less of a protection than general language in terms of service

Consequences for musicians

If Google wins, it will set a dangerous precedent. Any content uploaded to a platform with terms of service can be used for machine learning without additional notice or compensation. Large AI companies will get the green light to use creative works as fuel for their models.

If musicians win, it could force AI companies to be more honest about the sources of their training data. Explicit consent from creators would be required to use their works for AI training. This would protect independent musicians, but could slow the development of the AI industry.

What this means

This dispute is the first serious test of how broadly companies can interpret user licenses when training AI. The outcome will determine whether copyright remains a protection for creators or becomes a convention superseded by terms of service. For independent musicians, it's a question of survival in the era of generative AI.
