How content farms invented a court case — and who repeated it

If you have read an AI-music legal explainer this year, you may have met "Bartz v. SoundAI" — described as a 2024 Second Circuit decision on audio fair use, cited as precedent for how the Suno and Udio lawsuits will play out.

We ran the name through CourtListener's opinion database and the RECAP archive of federal filings. Zero results. Not a sealed case, not a mis-numbered docket — nothing. A real Second Circuit decision would appear in the opinions database as a matter of course.

Where it came from

There is a real case with a similar name: Bartz v. Anthropic PBC, filed in the Northern District of California by book authors, with a widely covered fair-use order in June 2025 and a settlement later that year. It concerns books and text models — not audio, not music, not the Second Circuit.

Somewhere between summarization pipelines and content-farm rewrites, "Bartz v. Anthropic" appears to have mutated into "Bartz v. SoundAI" — a courtroom that never sat, deciding a question no court has yet decided. The invented citation then propagated across sites that cite each other instead of primary documents.

Why it matters

The actual question — how fair use applies to training music-generation models — is still open. The UMG-led cases against Suno and Udio are active, and no appellate court has ruled on the merits. Anyone telling you the precedent is settled is citing a case that does not exist.

Every legal record in our Index links its docket. When a claim cannot be traced to a primary document, the record says so — that is the entire point.
