Deezer is fighting against slop with a tool that detects AI music on streaming platforms

Deezer has launched a free online AI music detector that checks playlists from 20 major streaming platforms for AI-generated tracks. It uses the same technology Deezer has been using to detect and tag synthetic music on its own service.

The tool is available in 27 languages, and it arrives as Deezer says nearly 75,000 AI-generated tracks are being delivered to it every day. That volume gives the launch a sharper edge than a simple playlist cleanup feature. It’s a way to put synthetic-song detection in front of listeners before the rest of streaming settles on common rules.

How much AI music is hiding in playlists

Deezer says 43% of people arriving from other streaming services already have AI-generated music in their playlists. For listeners, the new scanner answers a basic question that most platforms still don’t surface clearly.

Users connect a streaming account, choose playlists, and review the results. Because the scanner works across 20 common services, Deezer can get its detection system in front of people who don’t use its app.

That stance lands while major music apps are testing how far they want to go with generative tools, including Spotify’s experiments around AI-made covers and remixes. Deezer is focusing on the cleanup job that follows, identifying AI songs after they’ve already entered a library.

Why would the industry license Deezer’s detector

Deezer says its detection technology can identify tracks from major generative music models, including Suno and Udio. It can also be expanded when the company has enough data examples from other tools.

The company says it has made progress on a broader system designed to catch synthetic content without a model-specific training set. That gives Deezer a business case beyond the public playlist scanner. It wants platforms, labels, distributors, and rights groups to use the same underlying technology to spot machine-made tracks before they distort discovery or payment systems.

What happens after AI tracks are tagged

Deezer says fully AI-generated music makes up only 1% to 3% of streams on its service, but it also says as much as 85% of those streams were fraudulent in 2025. When Deezer finds stream manipulation, it excludes those plays from royalty payments.

The company has already removed AI-generated tracks from algorithmic recommendations and editorial playlists. Broader steps, including supplier policy changes or demonetization, are still under review. For listeners and the industry, Deezer’s practical message is clear. Detection has to happen before trust, royalties, and recommendations can be cleaned up.
