Deezer releases a free AI-music detector for Spotify playlists

Deezer has launched a tool for finding AI music in playlists. The detector is free and integrates with Spotify, Apple Music, YouTube Music and about twenty other streaming platforms. Anyone can now see how many neural-network-generated tracks have slipped into their music library.

How the detector works

The tool analyzes the audio and looks for signs of synthesis typical of modern neural networks: flaws in microdynamics, artifacts in the frequency spectrum, and unnatural transitions between sections of a track. The user logs in through an account on any supported streaming service, and the detector scans playlists automatically in the background. The result is a report with the percentage of suspicious tracks and a list of them.

Deezer does not disclose the full details of the algorithm, but says it trained the model on hundreds of thousands of real AI tracks collected over the past two years. That lets it catch music made by popular generators such as Suno and Udio, as well as by lesser-known tools.

Which platforms are supported

The detector works with the major streaming services and their competitors:

• Spotify
• Apple Music
• YouTube Music
• Amazon Music
• Tidal
• Deezer
• SoundCloud
• LastFM
• Pandora
• iHeartRadio

It also works with about a dozen regional and niche services. That gives users freedom to choose a platform, but it also shows the scale of the problem: AI music is not piling up in one place but spread evenly across the whole industry.

Interestingly, Deezer lets you scan other people's playlists if you have the link. That can help playlist curators who want to verify the quality of their content, and it is less useful for people who simply love music and would rather not know the truth.

Why the problem has grown worse

AI music is flooding streaming services at an exponential rate. Automatically generated tracks are cheaper than the work of a real producer, so some musicians and labels mass-upload AI slop to collect streams and royalties. Streaming services are fighting back: Spotify blocks obvious bots and suspicious accounts, but the line between well-made AI music and a live recording keeps blurring.

Deezer's detector is not a platform filter but a tool for listeners themselves. It amounts to an admission that platforms have no accurate server-side filters and probably never will.

What this means

The AI-music problem is moving into the public sphere. Listeners can now check whether their playlist is contaminated, and streaming services acknowledge the need for transparency. But this is not the end of the problem. Detectors go stale quickly: the better music generators get, the harder they are to spot. History shows that AI-content detection and synthesis are locked in a constant arms race. Deezer's tool is useful today, but tomorrow music generators will simply adapt to slip under the radar.
