Sony and Warner Chappell Want Up to $150,000 for Every Song Claude Was Trained On
This isn't Anthropic's first music copyright fight. Concord Music Group and other publishers sued in 2023 over roughly 500 songs' worth of lyrics, and that case is still working through the courts. What's new here is scale: Sony and Warner Chappell are alleging an order of magnitude more works, tied to the same torrenting playbook that already cost Anthropic a $1.5 billion settlement with book authors.
Named songs in the complaint include Bill Withers' "Ain't No Mountain High Enough," Survivor's "Eye of the Tiger," Bruno Mars' "Uptown Funk," and Mariah Carey's "All I Want for Christmas Is You," per Music Business Worldwide.

This is not the Suno lawsuit
It's easy to lump every AI-and-music lawsuit together, but Sony and Warner Chappell's case against Anthropic is a different fight from the labels' case against Suno. Suno and Udio are accused of training AI to generate new songs that sound like copyrighted recordings. Claude doesn't generate music at all. This suit is about whether Anthropic was allowed to feed songwriters' lyrics and compositions into a text model's training data in the first place, regardless of what Claude does with them afterward.
How the two music cases against Anthropic compare
| Concord Music Group v. Anthropic (2023) | Sony/Warner Chappell v. Anthropic (2026) | |
|---|---|---|
| Scale alleged | ~500 songs' worth of lyrics | "Tens of thousands" of compositions |
| Core claim | Unauthorized use of lyrics in training and outputs | Mass torrenting and scraping to acquire training data |
| Status as of this article | Ongoing; publishers moved for partial summary judgment in March 2026 | Just filed, no response from Anthropic yet |
| Individual defendants | Anthropic PBC only | Anthropic, plus co-founders Dario Amodei and Benjamin Mann |
Why the torrenting allegation matters more than the lyrics one
Courts have generally been more sympathetic to AI companies on the fair-use question of training on lawfully-obtained copyrighted text than on the separate question of how that text was acquired. Anthropic's $1.5 billion settlement with book authors turned on the same distinction: training itself was found fair use in that case, but downloading pirated books first was not. Sony and Warner Chappell's complaint leans hard on that same acquisition question, alleging specific torrenting activity rather than resting the case on the training itself.
What are Sony and Warner Chappell accusing Anthropic of?
Illegally torrenting, scraping, and downloading tens of thousands of copyrighted musical compositions to train Claude, without a license from the publishers.
How much money are they seeking?
Up to $150,000 in statutory damages per infringed song, plus $25,000 for each alleged instance of removing copyright management information. Neither the publishers nor the complaint states one final total dollar figure.
Is this the same lawsuit as the Suno one?
No. Suno and Udio are accused of generating AI music that resembles copyrighted recordings. This case is about whether Anthropic was allowed to use song lyrics and compositions as text-model training data, unrelated to music generation.
Has Anthropic responded?
An Anthropic spokesperson said the company disagrees with the publishers' claims and intends to defend itself in court, without addressing the specific allegations.
Is this Anthropic's only music copyright lawsuit?
No. Concord Music Group and other publishers sued in 2023 over roughly 500 songs, and that case is still active. Sony and Warner Chappell's 2026 suit is separate and alleges a much larger scale.
