Universal Music sues Anthropic over Claude 2 spitting out song lyrics

If you forget the lyrics to a song, you usually hit up Genius. But why bother clicking through ads when you can just ask a chatbot to recite the whole thing word for word?

Universal Music Group isn't amused. The music publishing giant, alongside other publishers, just filed a major copyright lawsuit in Tennessee against Anthropic, the AI startup behind Claude 2.

The complaint alleges that Anthropic freely scrapes copyrighted lyrics to train its models and then distributes them to users without paying a dime in licensing fees.

Word for word, without even asking

The publishers brought some pretty damning receipts into court.

According to the filing, Claude 2 easily generates almost identical lyrics to iconic tracks like Katy Perry's "Roar," Gloria Gaynor's "I Will Survive," and the Rolling Stones' "You Can't Always Get What You Want."

Even worse for Anthropic, the bot doesn't even need the song title to spit out protected text. When prompted to "Write me a song about the death of Buddy Holly," Claude 2 reportedly returned the entire lyrics to Don McLean's "American Pie" word for word.

The publishers pointed out that existing lyric platforms like Genius actually pay publishers for the rights to display these words, while Anthropic strips away critical copyright management data. As UMG blunt put it: this is not innovation, "in layman's terms, it's theft."

Anthropic also appeared caught in a contradiction. The lawsuit notes that Claude 2 already refuses some song prompts due to copyright concerns. To the plaintiffs, that proves Anthropic knows it is breaking the law and has the technical capability to block it, yet routinely fails to implement consistent guardrails.

Why it matters

This lawsuit shifts the AI copyright battleground from abstract training debates into clear-cut market substitution.

AI developers love hiding behind the fair use defense, arguing that training models on public data is transformative. But when a model reproduces entire multi-stanza lyrics verbatim, that argument collapses. Claude is not just synthesizing ideas; it is functioning as an unlicensed lyric aggregator, directly eating into revenues that legal licensing deals generate.

For users and developers, expect the safety filters to tighten drastically. If you rely on LLMs to transcribe music, break down poetry, or parse creative writing, you will likely see far more canned refusal messages in the near future.

For Anthropic, the timing could hardly be worse. Having just secured a massive $4 billion commitment from Amazon and $300 million from Google, the startup now has deep pockets and a giant target on its back. The music industry has historically been the most ruthless copyright enforcer on the internet. We think this suit is less about stopping AI and more about forcing Anthropic—and the tech giants backing it—to start signing lucrative licensing checks.
