Will Deezer flag my track as AI generated?
Deezer runs the most aggressive AI labelling programme of any major streaming service, and a lot of what artists believe about it is wrong. This page sets out what the system does, what it does not do, and what genuinely puts a release at risk.
The short version. An AI label on Deezer does not remove your track and does not, by itself, stop your royalties. It removes the release from recommendations. What actually costs money is being caught in stream manipulation, which is a separate system.
What Deezer built, and when
Deezer announced an in-house detector for fully AI-generated music in January 2025, alongside two patent applications filed in December 2024. The public labelling system launched in June 2025, and Deezer described it as the first of its kind on a music streaming service.
The volume figures Deezer has published since tell the real story of why they built it:
| Date | Fully AI tracks delivered per day | Share of daily deliveries |
|---|---|---|
| January 2025 | about 10,000 | about 10% |
| April 2025 | over 20,000 | 18% |
| January 2026 | about 60,000 | about 39% |
| April 2026 | about 75,000 | about 44% |

That last distinction matters more than any other number on this page. In April 2026 Deezer put fully AI-generated music at 44% of daily deliveries but only 1% to 3% of actual streams. AI music is flooding the delivery pipe, not the listening.
What the label actually does
Three things happen, and they are not the three things most artists assume.
1. The label is applied at album level
Deezer's own wording describes tagging "which albums include fully AI generated tracks". If one track on your EP is flagged, the notice appears on the release, not on that track alone.
2. The release is pulled from recommendations, not from the catalogue
Deezer excludes fully AI-generated tracks from algorithmic and editorial recommendations, which means Flow and Deezer's own playlists. The music stays searchable and stays on your artist page. Being labelled is not being removed, and anyone telling you otherwise is guessing.
3. Royalties are cut for fraud, not for being AI
This is the point that gets mangled everywhere. Deezer says it excludes streams from royalty calculation when it detects manipulation. It does not say it refuses to pay AI tracks. A labelled track that gets listened to normally is still paid.
The reason the two get confused is that Deezer reported that up to 85% of streams on fully AI-generated tracks in 2025 were fraudulent, against 8% across the whole catalogue. AI tracks and stream farms overlap heavily, so in practice a lot of AI music loses royalties. But the mechanism is the fraud detection, not the label.
So what actually gets a track flagged?
Deezer's research team published the mechanism, which is unusual and worth reading if you want to stop guessing. Their detectors key on periodic spectral peaks left behind by neural vocoders and codecs: the upsampling step in these models inserts zeros, which periodises the spectrum and replicates an energy peak at regular intervals.
The practical consequence is the thing most artists never hear: the detector is not identifying "music made by an AI". It is identifying the signature of a neural vocoder in the rendering chain. If your track never passed through one, there is nothing for that detector to find. If it did, for any reason, the signature is there.
That is also why "I only used AI for the lyrics" or "I only used it for a reference demo I then replayed" generally does not trigger anything: no generated audio, no vocoder signature.
What Deezer's own researchers say about the limits
Deezer Research published detection results at ICASSP in January 2025 showing 99.8% accuracy on their own test set, and then showed that performance collapsing under ordinary audio manipulation. They also found that transfer to unseen generator families gave results of "almost always" 0%, and concluded that "there will always be an unseen manipulation or generation method", describing the field as a cat-and-mouse game.

Take that seriously in both directions. It means a detector's headline accuracy is only meaningful against a named list of generators at a named date. It also means anyone selling you a service that "hides" AI from a detector is selling you a manipulation that the platform's own researchers published themselves, against a team that ships model updates for a living.
If you make music with humans and you are worried
The realistic risk for a human artist is not Deezer's label. It is a distributor flagging you before the release ever ships, which happens and is much harder to argue with. We wrote separately about what to do when a track is wrongly flagged as AI, including what evidence actually works.
Two habits reduce the risk at almost no cost. Keep your project files, stems and a dated session screenshot for anything you release. And if you use AI-assisted mastering, know that it is the one production tool with published evidence of pushing human tracks over detection thresholds.
If you release AI-generated music
Declare it. Every major distributor now asks, the declaration is contractual, and a false declaration is a much larger problem than a label. Deezer's system is designed around fully AI-generated tracks being findable and payable when they are listened to honestly. The thing that removes your money is the stream manipulation, and that is a choice you control.
