This is a tracked list of every major AI music copyright lawsuit filed since the generative AI boom began. It is maintained for ML teams, legal counsel, investors, and journalists who need to understand the legal landscape without wading through every case filing. Last updated April 9, 2026.
The list is organized by case and includes filing date, court, parties, statute, damages sought, current status, and any settlement terms. Sources are linked where available. If a case is not on this list, it either (a) has not been filed or (b) is below the threshold of commercial relevance for the enterprise buyers this post is written for.

Cases involving voice cloning and performer rights

Non-litigation notable: Scarlett Johansson and OpenAI "Sky" voice
Status: Not a lawsuit.
Background: In May 2024, Scarlett Johansson objected to OpenAI's "Sky" voice as resembling her own. OpenAI paused the voice voluntarily. No legal action was filed. This is frequently misremembered as a lawsuit but it was a legal demand letter only.
Cases involving AI and music training data broadly
Suno amended complaint allegations (stream-ripping)
The September 22, 2025 amended complaint in the Suno case alleges that Suno obtained training data by circumventing YouTube's rolling cipher DRM through stream-ripping. This adds DMCA §1201 claims to the existing copyright claims and materially increases Suno's legal exposure. The allegation is specific enough that it has become a teaching example for why stream-ripping is a particularly poor training data strategy for AI music companies.
Lyria 3 indie artist suit against Google
Indie artists sued Google alleging that YouTube's catalog was used to train Google's Lyria 3 music generation model. Google claims Lyria 3 was trained on "partner-licensed data and permissible content from YouTube." The case is active and disputed.
What this list tells you
Reading the list end to end, a few patterns become visible.
- 2024 was the year of complaints. 2025 was the year of rulings. 2026 is the year of settlements. The legal landscape compressed a decade of traditional copyright litigation into 24 months.
- Pirated training data is the consistent loser. Every ruling that has gone against an AI defendant has centered on the provenance of the training data. Courts have been willing to entertain fair use for legitimately acquired data and have consistently rejected it for pirated data.
- European courts are moving faster than U.S. courts. The first substantive copyright ruling against OpenAI happened in Munich, not New York or San Francisco.
- Settlements are structured around licensing, not damages. The Warner-Suno and UMG-Udio deals include ongoing licensing relationships, not just payment of damages. The future of the AI music industry is being priced as a long-term revenue stream for rightsholders, not a one-time settlement.
- Voice cloning is a lagging indicator. The ElevenLabs settlement was the first significant voice cloning case to resolve. More will follow. Voice rights litigation is structurally behind music rights litigation by about 12-18 months.
What to watch in the next 12 months
- The Sony Music cases against Suno and Udio (still active)
- Any ruling in the NYT v. OpenAI case
- Enforcement actions under the EU AI Act (begins August 2026)
- New voice cloning cases targeting specific products
- The NO FAKES Act (federal voice rights legislation)
- Lyria 3 indie artist class action ruling or settlement
- New cases filed as the Training Data Summary Template disclosures become public
How this list affects your data strategy
If you are building a music or voice AI product and trying to decide how to handle training data, the list above should answer most of the "is this risky?" questions. Training on scraped or pirated data is the common factor in every major loss. Training on licensed data has not produced a single adverse ruling. The data is unambiguous.
At The Vocal Market, our enterprise vocal dataset licensing program exists specifically as the licensed alternative for vocal AI training. Every recording in the catalog was contributed by a professional vocalist under a timestamped agreement that explicitly authorizes AI training use. The consent documentation is auditable. The commercial terms are designed to survive the due diligence phase of any future litigation or acquisition.
If you want a sample of the dataset and accompanying compliance documentation, request one here. We will send it within two business days along with the licensing terms your legal team will want to review.
