Sony is reportedly developing a tool that can identify original music inside AI-generated songs and estimate how much each source influenced the output. The aim is to make attribution more measurable when synthetic tracks draw from copyrighted catalogs.
The timing is notable. As AI music gets easier to generate and distribute, rights holders and platforms are looking for enforcement options that scale beyond takedowns.
How Sony’s tool is said to work
According to a report by The Verge, Sony’s system is designed to operate in both cooperative and non-cooperative scenarios, and the company has not decided when it will put the technology into commercial use.
In the cooperative case, Sony’s system would analyze training data with the developer’s access. In the non-cooperative case, it compares an AI-generated track against existing catalogs to estimate likely source works and their relative influence, according to Music Business Worldwide and Digital Trends.
The most consequential piece is the “no cooperation required” pathway. If it performs reliably, it gives rights holders a repeatable way to argue influence even when training datasets stay opaque.
Why attribution is becoming the negotiating lever
Platforms are tightening rules in parallel, and the pressure is coming from courts and distributors. According to Ars Technica, major labels sued Suno and Udio in June 2024, alleging copyright infringement tied to training and outputs. That legal fight has turned attribution into a negotiating point: deals change when rights holders can tie a model’s output back to specific works with more than inference.
Similar pressure has been building across the market as AI-generated music spreads. Deezer is demonetizing large volumes of streams tied to fully AI-generated music and plans to commercialize its detection tech, a signal that streaming platforms don’t want synthetic tracks diluting royalty pools.
Bandcamp has also decided to ban music generated wholly or in substantial part by AI, alongside action by Sweden’s official charts against a track ruled mainly AI-generated. Taken together, the moves show tightening rules across the distribution chain, from storefronts to charts.
Sony has not shared a rollout timeline. Still, if attribution becomes credible and hard to evade, it could reshape licensing talks by making “influence” harder to deny and easier to price.
