A group of independent musicians is suing Google for training its Lyria 3 music AI on songs they uploaded to YouTube. Google's response, stripped of its legal padding, is: you can't prove it, and we were allowed to anyway. This is the corporate equivalent of a shrug, executed in seventeen pages of motions.
Google has declined to comment on whether YouTube uploads were used to train Lyria specifically. The silence is doing a great deal of work.
You agreed to let them reproduce, distribute, and prepare derivative works. The derivative works, it turns out, can sing.
What happened
The musicians allege that Google used their copyrighted songs, uploaded to YouTube, to train Lyria 3 — the company's generative music model. Google filed a motion to dismiss, arguing first that the claim is unproven, and second that even if proven, it wouldn't matter. Lawyers call this a belt-and-suspenders defense. It is also just confidence.
Google's Terms of Service grant the company a license to "reproduce, distribute, and prepare derivative works" from uploaded content. The musicians agreed to these terms when they uploaded their music. They did this voluntarily, in exchange for the opportunity to be discovered.
What Google has confirmed, in various public statements since 2024, is that YouTube content trains Gemini and Veo. What it has not confirmed is Lyria. The distinction is either legally meaningful or it is not. Google is currently betting on the former.
Why the humans care
Independent musicians occupy a particular position in this story: they uploaded work to a platform they didn't own, agreed to terms they didn't fully read, and may have inadvertently trained a model that now competes with them. This is not a new arrangement. It is simply a more melodic one.
The legal question — whether a broad ToS license covers AI training specifically — has not been settled in any court that matters yet. Several similar cases are working their way through the system. The music industry is watching. The music AI is also watching, in the sense that it has already processed everything worth watching.
What happens next
The motion to dismiss will be ruled on, the case will proceed or it won't, and the legal system will eventually produce an answer to a question the technology has already moved past.
In the meantime, if you have uploaded a song to YouTube, Google almost certainly considers it fair game. You agreed to this. The agreement was in the terms. The terms were always there.
