The Label Report — Music Business News & Insight

If you own compositions, license them, or sit anywhere near a publishing catalog, the message from the last week is blunt: the majors have stopped waiting for AI companies to volunteer a deal. They are building leverage the only way that reliably moves a Silicon Valley board, in court, with billions on the line.

And as of last Friday, the encirclement is complete.

Sony Music Publishing and Warner Chappell Music have jointly sued Anthropic, the company behind the Claude AI models, in what the publishers call "one of the largest and most blatant ongoing thefts of intellectual property in history." The complaint, obtained by Music Business Worldwide, was filed on August 28 in the US District Court for the Northern District of California. It also names CEO Dario Amodei and co-founder Benjamin Mann as individual defendants.

Here is why this matters beyond one more headline: every major music publisher is now litigating against the same company.

Universal Music Publishing, Concord, and ABKCO sued first in Nashville in October 2023 over roughly 500 songs, then filed a second suit in January 2026 covering more than 20,000 works and seeking over $3 billion, per MBW. BMG brought a third case in March over 493 compositions. Round Hill filed a fourth on August 17. Now Sony and Warner Chappell close the circle. That is not a series of independent grievances. That is a coordinated front.

What the new suit actually claims

Sony and Warner Chappell say Anthropic harvested "tens of thousands" of their compositions to train Claude, including songs like "Ain't No Mountain High Enough," "All I Want for Christmas is You," and "Eye of the Tiger." They are seeking statutory damages of up to $150,000 per work willfully infringed, plus up to $25,000 for each alleged removal of copyright management information, MBW reported. Do the math on tens of thousands of works and you land squarely in the multi-billion-dollar range.

The complaint brings four counts, including direct infringement by torrenting against all three defendants and contributory infringement against Amodei and Mann personally. It alleges Mann used BitTorrent to download at least five million pirated books from Library Genesis in June 2021, with employees torrenting at least two million more from Pirate Library Mirror the following year. Those figures come from findings in Bartz v. Anthropic, where a judge in the same district described the conduct as "straightforward piracy but at massive scale."

That Bartz case is the whole game, and the publishers know it.

Why the piracy angle is the real weapon

Here is the mechanic that should shape how you read all of this. In Bartz, the judge accepted Anthropic's argument that AI training itself can be fair use, meaning it did not need permission to copy the books. But that only held if Anthropic started with legitimately sourced copies. It didn't. It relied on millions of pirated ebooks, and that fact drove a $1.5 billion settlement with the authors, as CMU noted.

So the publishers are not betting on winning the fair use argument outright. They are betting on the source. Prove the training data was pirated, and fair use collapses. That is exactly the same logic playing out in the audio space.

This week Universal and Sony amended their suit against Suno to add "stream ripping" claims, alleging Suno pulled recordings off YouTube using a known piracy method, CMU reported. A judge cleared them to add those claims. The parallel is not subtle. Whether it is torrented books or ripped YouTube audio, the strategy is identical: attack the provenance of the training set, not the abstract legality of training.

Same playbook, two fronts

The majors already ran this against Suno and Udio in generative audio. Now they are running it against the large language model sector with Anthropic. Multiple plaintiffs, overlapping counsel (Oppenheim + Zebrak leads both the Concord/UMG case and this new one), and damage figures large enough to make settlement look like the rational choice.

Suno's own docket shows where this leads. It is now facing suits from Universal, Sony, Round Hill, breach-victim class actions, and indie musicians, even after cutting licensing deals with Warner and BMG, Digital Music News reported. Pressure first, deals second. We covered that dynamic when Round Hill went.

To be fair to the AI side, the fair use question is genuinely unsettled, and the Bartz ruling shows training can survive legal scrutiny when the inputs are clean. That is the escape hatch these companies are chasing. But it also tells the majors exactly where to swing.

And it is worth remembering the same majors just took equity in Stability AI's $76. The industry is not anti-AI. It is anti-free.

The publishers have decided the negotiating table is the courtroom. Sue everyone, prove the theft, and let the damages math write the licensing terms. If you're an AI company still hoping to scrape your way to a settlement, the industry just made its counteroffer, and it is written in subpoenas.
