Short answer: Suno has acknowledged that its music-generation models were trained on music gathered from the open internet and that much of it was copyrighted, including music owned by major record labels. It has not admitted that the use was unlawful. Suno argues that copying recordings to teach a model to generate new music is protected by fair use. The labels suing Suno argue that the company copied and commercially exploited protected recordings at enormous scale without licenses. No U.S. court ruling identified through August 18, 2026, has finally resolved that dispute.
What Suno actually admitted
In an August 1, 2024 filing and public response, Suno said it trained models on medium- and high-quality music available on the open internet and acknowledged that much of that material was copyrighted, including recordings owned by major labels. TechCrunch reported Suno’s statement; the allegations appear in the RIAA’s complaint.

That statement establishes a factual position, not a court finding. “Open internet” describes how material could be accessed; it does not mean the material was public domain, licensed for artificial-intelligence training, or free of platform restrictions. The available materials do not establish that Suno knew the owner of every recording or that its historical corpus contained only sound recordings. Depending on the files and processing involved, separate rights in compositions, lyrics, metadata and master recordings may also matter.
Suno’s user terms separately require customers to have the necessary rights for uploads. That consumer rule does not answer whether Suno had permission to obtain and copy its earlier training data.

Why the lawsuits matter
On June 24, 2024, the Recording Industry Association of America announced lawsuits against Suno and Udio. The labels allege large-scale, unauthorized copying of decades of popular sound recordings to build commercial generative-music services. They argue that an unlicensed company should not be able to use those catalogs to sell a competing music product while calling the copying fair use. See the RIAA announcement and complaint.
The cases are not limited to whether a generated track sounds like a particular hit. They also concern the acquisition and processing of the underlying recordings, possible competition with licensed music, and whether record companies have a current or reasonably foreseeable market for licensing catalogs to AI developers.
Suno’s fair-use theory
Suno’s argument is that a model does not simply redistribute the original recordings. It processes examples to learn musical relationships and then generates new audio in response to a prompt. Suno’s chief executive compared that process with a child listening extensively to rock music and learning to write rock songs, as summarized by MusicRadar.
That analogy addresses the creative result, but not every legal step required to produce it. A court must analyze the copies made to acquire and train the model, the purpose and character of the use, the nature of the works, the amount copied, and the effect on existing or potential markets under 17 U.S.C. § 107.

1. Purpose and character
Suno’s best argument: Training is transformative because the system uses works to build a new generative tool rather than serve the original recordings unchanged.
The labels’ response: Suno is a commercial service whose revenue depends on generated music. The alleged copying directly supports a product that can compete with licensed recordings and commissioned music. Commercial purpose is relevant but does not automatically defeat fair use.
2. Nature of the works
Music is highly creative, which generally weighs more heavily against fair use than use of factual material. The rights can be distinct:
- Sound recording: the recorded performance or master.
- Musical composition: melody, harmony and structure embodied in the song.
- Lyrics: separately protected expression.
- Ownership: a label may own a master while a songwriter or publisher controls composition rights.
The 2024 RIAA case principally emphasizes sound recordings, while other claims or licensing arrangements may involve additional rights. The U.S. Copyright Office’s AI initiative tracks these broader copyright questions.
Rank #3
3. Amount and substantiality
Training may require acquiring complete recordings even if the deployed model does not distribute those files. Suno can argue that the model retains patterns rather than playable copies. The labels can respond that complete copying, the scale of the corpus, the quality of the files and any memorization are all significant.
The question is not simply whether the model used “small snippets.” Evidence could include how many works entered the pipeline, whether full recordings were downloaded, which expressive elements were retained, and whether the system can reproduce recognizable material.
4. Effect on markets
This may be the most consequential economic fight. Suno can characterize its product as a new tool that does not replace any particular master recording. The labels can argue that generated music competes with licensed catalog music in advertising, video, background use and other commercial settings, while also undermining a potential market in which rights holders license catalogs for AI training.
Discovery materials show disputes over licensing agreements, AI licensing strategy, alleged market harm and the labels’ efforts to obtain “no AI” provisions. A Justia docket filing records those continuing issues.

Questions beyond the four factors
Training copies versus infringing outputs
These are separate questions:
- Was it lawful to acquire the recordings?
- Was it lawful to store and process them during training?
- Does a particular output reproduce protected expression from an existing song or recording?
- Did a user supply infringing lyrics, audio or another protected input?
Originality in some outputs would not automatically legalize unlicensed training. Conversely, a finding that training is protected would not immunize an output that reproduces protected lyrics, melody or a recognizable recording.
Memorization and regurgitation
Potential evidence could include near-identical melodies, lyrics, arrangements or recordings; reproduction after unusually specific prompts; fingerprint matches; internal evaluations showing memorization; and safeguards that detect or block recognizable material. Public materials identified here do not establish how often Suno’s models memorize particular songs, so that issue should not be treated as proved either way.
Access and provenance
Courts may also examine where files came from, whether downloading or scraping bypassed technical restrictions, what platform terms allowed, and whether the company maintained records showing provenance and permissions.

The U.S. Massachusetts litigation remained active as of August 18, 2026. Docket materials show continuing discovery about training data, licensing, market harm and Suno’s defenses, including arguments involving alleged copyright misuse and anticompetitive conduct. Those are litigation positions, not findings that the labels acted unlawfully. No final U.S. fair-use judgment was verified in the materials cited above.
Best Value
A separate development was reported on July 31, 2026, when the Munich Regional Court reportedly ruled against Suno in a case brought by GEMA concerning works represented by the German collecting society. MusicRadar’s report describes licensing-related remedies and a finding of unlawful conduct under German law.
That decision is not a U.S. federal judgment. It may involve different statutes, evidence, plaintiffs and remedies, and it does not control the Massachusetts fair-use case. It could nevertheless increase commercial and litigation pressure on Suno and other AI-music companies. The final German text, appeal status and precise scope of any order should be checked before relying on them.
What this means for Suno users
| Plan or issue | What Suno says | Practical limitation |
|---|---|---|
| Free | $0 per month, 50 daily credits; no commercial use. | Free-tier songs are intended for personal, non-commercial use. |
| Pro | $8 per month shown on the pricing page when checked; 2,500 monthly credits and commercial-use rights for new songs made while subscribed. | Commercial-use rights do not guarantee copyright protection. |
| Premier | $24 per month shown when checked; 10,000 monthly credits and commercial-use rights for new songs made while subscribed. | Prices, credits and features can change. |
| Later subscription | Subscribing later generally does not make earlier free-plan songs commercially cleared. | See Suno’s distribution guidance and retroactive-rights guidance. |
Suno says paid-plan songs may be monetized and distributed, but its commercial-rights guidance warns that commercial permission is not the same as copyright protection. Its copyright explanation says eligibility varies by region and that wholly AI-generated music may not qualify for U.S. copyright. Human-authored lyrics, substantial editing, arrangement or other creative contributions can present different questions.
- Do not upload a backing track, lyrics or sample unless you have the necessary rights.
- Do not assume a paid plan clears a third party’s melody, voice, lyrics or recording.
- Check a distributor’s current AI-content policy; acceptance by a distributor is not proof of copyright clearance.
- A subscription does not license the historical music used in Suno’s model training.
Bottom line
Suno’s position is not that copyrighted music is free to use. It is that copying copyrighted music to train a generative model can be legally protected even without a license. The labels argue that the scale of copying, the creative nature of the recordings, Suno’s commercial purpose and damage to actual or emerging licensing markets defeat that defense. The reported German ruling adds pressure, but it does not decide the U.S. cases. The central fair-use question remains unresolved in the U.S. materials available through August 18, 2026.
