Deezer Launched Free AI Music Detector for Spotify Playlists

Deezer launched a tool for finding AI music in playlists. The detector works for free and integrates with Spotify, Apple Music, YouTube Music, and approximately twenty other streaming platforms. Now anyone can find out how many AI-generated tracks have ended up in their music library.

How the Detector Works

The tool analyzes audio material and searches for signs of synthesis characteristic of modern neural networks—defects in micro-dynamics, artifacts in the frequency spectrum, unnatural transitions between parts of a track. Users authenticate through an account on any supported streaming service, and the detector automatically scans playlists in the background. The output is a report showing the percentage of suspicious tracks and their list.

Deezer doesn't disclose full algorithm details, but claims it trained the model on hundreds of thousands of real AI-generated tracks collected over the past two years. This allows it to catch music created by both popular generators like Suno and Udio, as well as less-known tools.

Which Platforms Are Supported

The detector works with major streaming services and their competitors:

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

As well as with approximately a dozen regional and niche services. This gives users freedom in choosing a platform, but at the same time demonstrates the scale of the problem: AI music doesn't accumulate in one place but is evenly distributed throughout the industry. Interestingly, Deezer allows scanning other people's playlists if you have the link. This can be useful for playlist curators who want to ensure the quality of their content, and less useful for people who simply love music and would prefer not to know the truth.

Why This Problem Has Worsened

AI music is flooding streaming services exponentially. Auto-generated tracks are cheaper than a real producer's work, so some musicians and labels are mass-uploading AI-generated content to earn streams and royalties. Streaming services are fighting this: Spotify blocks obvious bots and suspicious accounts, but the line between high-quality AI music and live recordings is becoming increasingly blurred. Deezer's detector is not a platform filter but a tool for listeners themselves. It's an acknowledgment that precise filters on the service side don't exist and probably won't.

What This Means

The AI music problem is moving into the public sphere. Listeners can now check whether their playlist contains AI-generated content, and streaming services acknowledge the need for transparency. But this is not the end of the problem. Detectors quickly become obsolete: the better music generators become, the harder they are to catch. History shows that AI content detection and synthesis are in constant arms race. Deezer's tool is useful today, but tomorrow music generators will simply adapt to evade detection.
