Deezer: Nearly Half of New Tracks on the Platform Are Fully AI-Generated

Deezer has revealed new data on the scale of AI-generated music on streaming platforms: 44 percent of tracks uploaded to the service every day are recordings created entirely by AI models such as Suno or Udio. The French platform is also drawing attention to its free detection tool, which works not only on its own library but also on playlists from Spotify, Apple Music and other services.

The scale of the phenomenon

The growth has been steep. As recently as January 2025, Deezer recorded about 10,000 fully AI-generated tracks uploaded per day. By September 2025, such recordings made up 28 percent of all daily uploads. Today, according to the platform, that share has reached 44 percent, or roughly 75,000 tracks a day. The company attributes this to the progress of music generators, which produce publish-ready tracks ever more cheaply and quickly.

How the detector works

Deezer has not disclosed the full technical details of its system, saying only that generative software leaves characteristic artifacts in the audio signal that cannot be removed without a noticeable loss of sound quality. Based on this, the system classifies tracks as fully AI-generated with a claimed accuracy of 99.8 percent.

The tool, called AI Music Detector, is available for free in the browser, with no need to create a Deezer account. Users simply provide a link to a playlist from one of the 20 supported streaming platforms, and the system scans up to 100 tracks at once, flagging which ones were created entirely using generators such as Suno or Udio.

No other company has followed our lead yet, so we decided to let everyone check whether their playlists contain synthetic music, regardless of which streaming platform they use - Alexis Lanternier, CEO of Deezer

Listeners can't tell the difference

Deezer and Ipsos also ran a blind test in which 97 percent of participants could not identify which of the tracks played had been created by artificial intelligence and which had been recorded by humans. This shows that the quality of generated music has become close enough to human recordings that telling them apart by ear is no longer possible for the average listener.

The same study found that 80 percent of respondents across eight countries believe AI music should be clearly labeled, and 73 percent would like to see such labels directly on streaming platforms. Deezer stresses that its goal is not to ban such recordings but to label them honestly, so that listeners can decide for themselves whether they want to hear them.

The fake plays problem

Although AI music now accounts for nearly half of daily uploads, its share of actual plays on Deezer remains small, at 1-3 percent. The platform explains this by noting that AI-generated recordings are automatically excluded from algorithmic recommendations and editorial playlists. A more troubling figure is a different one: up to 85 percent of the plays that AI tracks do register involve suspicious, artificial activity, meaning bots and fake streams generating royalties.

It is this mechanism that worries the music industry most. Automatic generators let platforms be flooded with thousands of tracks a day at virtually no cost, and some of this music exists solely to siphon payouts from the royalty pool, at the expense of real artists whose recordings are paid out of that same pool of plays.

What this means for Polish listeners

Deezer's detector also works on playlists from Spotify and Apple Music, the most popular services in Poland, so Polish users can check their playlists regardless of which platform they use day to day. This matters because domestic streaming services do not yet offer tools of their own, and the labeling of AI content is only just beginning to appear in EU regulations, which start covering audio content as well from August 2.

For music creators and publishers in Poland, the growing share of generated tracks also creates a practical problem: it is becoming harder to tell at a glance which recordings on editorial playlists or in recommendations are fully human-made and which are partly or entirely generated. Tools such as Deezer's detector are therefore becoming a reference point not just for listeners but for the platforms themselves, which must decide how to treat such music within their payout systems.

Deezer says it will keep developing its detection system as music generators become harder to unmask. The company has not disclosed, however, whether it plans to offer the technology to other streaming platforms on a commercial basis, or whether further detector updates are planned in response to new audio-generating models.
