Deezer's AI Music Fight
Deezer Launches Free Web-Based AI Detector to Combat Fraudulent Music and Protect Artists

Key Points

Deezer said it attempted to sell/license its detector to other parts of the industry, but “No other company has followed our lead yet,” after limited commercial uptake; it also noted an earlier licensing effort tied to its January partnership with French royalty agency Sacem.

Deezer’s detection system is specifically claimed to recognize tracks tied to major generative music models—naming Suno and Udio—rather than relying only on generic “AI” tags.

To justify the stakes, Deezer cited a 2024 CISAC study saying that by 2028, 25% of artist revenues (about $4.6 billion/€4 billion annually) could be diverted by AI-generated songs.

Deezer added more detail on the composition of AI uploads: it claims synthetic tracks represent 44% of its new music delivery, and that “up to 85 percent are fraudulent,” i.e., copies of human artists’ songs.

For users, the flow is not only “scan and alert”: after granting access on Deezer’s detection site, Deezer imports the playlists, scans them for AI content, flags matches, and provides an option to share the results.
Deezer launched a free web tool on June 11, 2026, that scans playlists from about 20 major streaming services — including Spotify and Apple Music — to flag AI-generated tracks. Digital Music News reported that users grant Deezer permission to import their playlists, after which the scanner checks for artifacts left by AI models and flags any matches.
The move comes as Deezer says nearly 75,000 AI-generated tracks arrive on its platform every single day. The company calls much of this content "AI slop" — synthetic filler that it says is crowding out human artists and draining their royalty payments. Rolling Out noted the tool supports 27 languages, making it one of the broadest consumer-facing AI detection tools in the music industry.
75,000 Daily AI Tracks Flood Deezer's Platform
Deezer says synthetic tracks now make up 44% of all new music delivered to its platform. Of those AI tracks, Deezer claims up to 85% are fraudulent — meaning they are copies or close clones of real human artists' songs, designed to siphon royalty payments. Lifehacker Australia reported that Deezer's system looks for specific digital artifacts left behind by AI to make its call.
Deezer says its detector is over 99% accurate at spotting tracks made by major generative music tools, specifically naming Suno and Udio. A 2024 study by CISAC — the global body for authors and composers — warned that by 2028, AI-generated songs could divert 25% of all artist revenues. That works out to roughly $4.6 billion per year pulled away from human musicians.
No Rival Platform Followed Deezer's Lead on Detection
Deezer did not build this tool in a vacuum. The company had spent most of 2024 and 2025 trying to license its AI-detection technology to other streaming services and music distributors. Those efforts saw "limited commercial uptake," according to Deezer. In plain terms: no other major platform bought in. Boca Raton Tribune noted that an earlier licensing push was tied to Deezer's January 2024 partnership with Sacem, the French royalty agency.
Deezer says that after rivals declined to act, it decided to go directly to users. The company said: "No other company has followed our lead yet." Rather than just tagging AI content like many competitors do, Deezer actively blocks AI tracks from its recommendation engine and editorial playlists. The new scanner brings that same logic to listeners on other platforms.
How the Scanner Works and What Users See
The process is simple. A user visits Deezer's detection website and grants permission for Deezer to import their playlist from another service — say, Spotify or Apple Music. Deezer then scans each track, flags any it identifies as AI-generated, and shows the results. Users also get an option to share those results. Digital Music News pointed out that Deezer directs users to a third-party tool called Tune My Music to help move playlists over.
Deezer found that 43% of users who migrate playlists from other services already have AI music embedded in their libraries — often without knowing it. That stat helps explain why Deezer built the tool for outsiders, not just its own subscribers. The scanner is free and works in 27 languages, lowering the barrier for listeners worldwide to check what is actually in their playlists.
A Royalty Crisis and a Customer Acquisition Play
The stakes for artists are real. The CISAC study projects that $4.6 billion in annual royalties could flow to AI-generated content by 2028 instead of to human musicians. Deezer has framed the scanner as a tool for protecting that money. Middle-tier genres like lo-fi, ambient, and background pop are most at risk, since those are the styles AI models replicate most easily and most often.
But analysts also see a strategic upside for Deezer. By requiring users to hand over their playlist data to run the scan, Deezer gets a direct look at what Spotify and Apple Music subscribers are listening to. That data is valuable. Whether the tool succeeds as a moral crusade or as a growth funnel — or both — Deezer has put a number on the AI music problem that the rest of the industry will now have to answer to.
