On May 16, 2024, Sony Music Group warned more than 700 AI developers, technology companies and music-streaming services not to use Sony-controlled content for artificial-intelligence training, development or commercialization without explicit permission.
The announcement was not a blanket rejection of AI. Sony Music Entertainment and Sony Music Publishing reserved their rights against unauthorized text and data mining, web scraping, copying, extraction and similar activity while saying that artists and songwriters could use AI responsibly as a creative tool.
What Sony announced
Sony took two related steps. First, it published a Declaration of AI Training Opt Out covering existing and future Sony Music content, subject to any specific authorization Sony might grant.

The recipients were described broadly as AI developers, technology companies, music-streaming platforms and other businesses involved in AI systems or services. The complete distribution list was not publicly established.
#1 Best Overall
According to TechCrunch, the letters said Sony had reason to believe that recipients or their affiliates may already have made unauthorized uses of Sony content. Sony asked companies to explain whether and how its material had been obtained and used, including whether it had entered training, development or commercial systems.
That wording matters. Sony was making an allegation and seeking information, not announcing a court finding that every recipient had infringed copyright.
What content did the warning cover?
The declaration was broader than a warning about recorded songs alone. It applied to content associated with both Sony Music Entertainment and Sony Music Publishing, including:
- Sound recordings
- Musical compositions and lyrics
- Audiovisual recordings
- Artwork, cover images and other images
- Metadata
- Other content controlled by Sony Music or its affiliates
The restricted activities included text and data mining, web scraping, reproduction, copying, extraction and similar uses for training, developing or commercializing AI systems. Sony’s declaration directs companies seeking permission or clarification to separate contacts for Sony Music Entertainment and Sony Music Publishing.

What does “opt out” mean?
Sony’s opt-out was a public assertion of non-consent and a reservation of rights to the fullest extent permitted by applicable law. In practical terms, Sony was telling companies not to treat publicly accessible music-related material as freely available for AI scraping or training.
It did not automatically remove Sony’s catalog from every dataset or model, and it did not make the legal position identical in every country. Copyright rules governing text and data mining differ by jurisdiction. Sony’s UK AI-use terms, for example, expressly reserve its website content from text and data mining under applicable law, including the framework derived from the EU Copyright Directive.
A rights reservation can establish a clear position, but it does not by itself decide whether a particular act of copying, model-training process or AI output is lawful worldwide.
Training is only one part of the dispute
Several separate questions are often compressed into the phrase “AI use of music.” They should be distinguished:
| Issue | Question |
|---|---|
| Training | Were recordings, lyrics, compositions, metadata or other works copied into a model-training dataset? |
| Input or retrieval | Did a user or system supply copyrighted material as a reference or retrieve it during operation? |
| Output imitation | Can the system reproduce lyrics, melodies, recordings, voices or other recognizable protected elements? |
| Distribution and commercialization | Was an allegedly infringing or misleading output released, monetized or streamed? |
Sony’s declaration addressed training broadly and also referred to AI development and commercialization. It did not establish that all AI-generated music is infringing, that every stylistic imitation violates copyright, or that a particular output necessarily copied a protected work.
Why the warning mattered
The move showed a major rights holder shifting from general concern about generative AI toward formal rights reservation, direct corporate notices, evidence-gathering and licensing pressure.
Sony’s position was that AI companies should obtain permission and provide appropriate control and compensation rather than assume that material found online could be used without restriction. That approach also created leverage for future licensing discussions involving authorized datasets, artist consent and transparent compensation.
In a later corporate presentation, Sony said it had sent more than 700 letters and issued more than 20,000 takedown requests involving AI-generated content on digital service providers during calendar year 2023. Those figures describe Sony’s broader reported enforcement activity; they should not be confused with a judicial determination that all of the targeted material was unlawful. See Sony’s 2024 business presentation.
What it meant for AI developers
A company using music or music-related data would need to examine more than whether a file was publicly accessible. Key questions include:
- Who controls the rights? A composition and its sound recording are separate rights interests. Permission for one may not cover the other.
- Where did the data come from? A licensed database, a streaming service, a public website and a user upload do not carry the same permissions.
- What is the purpose? Training, evaluation, product development, output generation and commercial distribution may raise different issues.
- Which laws apply? The location of copying, the provider and the service can affect the analysis.
- Can the company document its sources? Dataset provenance, licenses, removal procedures and responses to rights-holder inquiries become central when ownership is disputed.
- What can the system produce? Controls may be needed for lyrics, melodies, recordings, artist names, voices and outputs that could mislead listeners about artist involvement.
Removing material after receiving a notice may reduce continuing exposure, but it does not necessarily resolve questions about earlier copying or training.

For creators, the announcement highlighted the difference between consenting to an AI-assisted creative workflow and allowing a company to exploit a catalog or identity without permission. It also underscored why ownership records matter: songwriting, publishing, master recordings, artwork and metadata may be controlled by different parties.

Sony’s public position left room for licensed and artist-directed AI use. Its objection was aimed at unauthorized exploitation, not at the technology itself.

The wider AI-music conflict
The May 2024 warning did not settle the broader copyright debate. It did not determine whether training copies are infringing in every jurisdiction, whether fair use applies in the United States, how model weights should be treated, or when style imitation becomes unlawful.
Later disputes made the conflict more visible. Sony Music, Universal Music Group and Warner Music Group sued the AI music companies Suno and Udio, alleging unauthorized use of copyrighted recordings to train their systems. Those proceedings were separate from Sony’s May 2024 letters and did not retroactively turn the warning into a legal judgment. The Associated Press reported on that later litigation.
The essential distinction
Sony Music’s message was not “AI is forbidden.” It was: Sony-controlled recordings, compositions, lyrics, images, metadata and related works should not be scraped, copied, extracted, trained on or commercially exploited for AI purposes without authorization, subject to the limits of applicable law.
