AI music lawsuits explained: the major cases, what they're about and what happens next

Last checked: 23 Oct 2026. This is a living page. We re-check each case against its docket or court announcements and date every change in the changelog. Filings make allegations; unless a row says a court ruled, nothing in it has been proven.

More than two years after the major labels first sued Suno and Udio, AI music is being fought over in courts in the US, Germany, Denmark and Canada. The cases mostly fall into three groups. One more, Reyna v. Suno, is a trademark claim whose facts aren't public. Rights owners (labels, publishers and collecting societies) say AI companies copied their catalogues. Independent artists have filed class actions of their own. And a few musicians are suing over their names and voices rather than copyright.

The cases at a glance

"None found" means we found no public date. It doesn't mean nothing is scheduled.

What are the courts actually deciding?

1. Is training fair use? This applies in the US only. Fair use lets you copy without permission if four factors favour it. The fourth, harm to the market for the original, is where these cases are fought. In 2025 two judges in San Francisco ruled for AI companies on training. Judge Alsup in Bartz v. Anthropic called training fair use, but not keeping a library of pirated books. Judge Chhabria in Kadrey v. Meta said a flood of AI output that competes with human work ("dilution") could be a winning argument, but found the authors had offered no evidence of it. The rights owners now point to the AI companies' own licensing deals as proof that a market for training licences exists. Sony's second Udio complaint lists deals with UMG, Warner, Merlin, Kobalt, Believe and the National Music Publishers' Association. The US Copyright Office has said that where licensing markets can meet AI training needs, unlicensed uses "will be disfavored". The Justice Department argues the opposite, at least for training on written works: in a 1 Sep 2026 filing in the New York Times' case against OpenAI, it called it "legally incorrect" to impose liability that would generally make AI training impermissible without licensing (our report).

2. How was the music obtained? Stream-ripping means downloading audio from YouTube by getting around its technical protections. Under US law (the DMCA's anti-circumvention rule) that can be illegal however the copies were later used. That claim survived early challenges in both Suno I and Justice v. Suno. Piracy is the same kind of argument, and it is the one behind Concord II.

3. Is the song inside the model? Europe has no fair use. In GEMA v. Suno, the Munich court found that six songs were reproducibly contained in Suno's models, and held that this "memorisation" counts as copying (our report). SOCAN's Canadian case targets outputs directly.

4. Who owns your name and voice? Isbell v. Suno relies on state publicity laws and Illinois' biometric privacy law. Those rights belong to the performer, whoever owns the recordings.

What each outcome would mean for independent artists

• If US courts call training fair use, what's left is how the data was obtained, what the outputs copy, and identity claims. Keeping evidence of outputs that copy your song becomes the most valuable thing you can do.
• If they don't, money flows through licences. So far those licences go to catalogue owners and to distributor programmes that artists opt in to. The Reservoir case shows how those deals are now used as evidence.
• If memorisation spreads as a theory in Europe, songwriters gain most where their collecting society holds AI rights in their works, as GEMA's did.
• If identity claims hold, artists who don't own their masters get a claim of their own. As the Isbell complaint is drafted, though, most of it depends on Suno's model responding to your name as a prompt.

Two rules decide who gets paid in any of these scenarios. In the US, you generally can't get statutory damages or legal fees for infringement that began before your work was registered with the Copyright Office, unless you registered within three months of release (17 U.S.C. § 412). And if any of these class actions is certified and settles, you are bound by the outcome unless you formally ask to be excluded (Rule 23).

What we think

The headline cases are rights owners against AI companies, and those cases will set the price of a training licence. Independent artists should watch the less famous rows. Justice, Woulard and Kogon are the only copyright cases in the table brought by independent musicians themselves, and a settlement in one of them could become the only AI licence many independents ever get. Register your releases, keep records of what you uploaded and where, and read every class notice that reaches you.
