Questions these episodes answer
Why does Deezer choose not to recommend fully AI-generated music?
Deezer built a detector for 100% AI-generated tracks and found their share of new deliveries rose from about 10% in January toward 20%. Rather than removing this music, Deezer decided not to recommend it, since the company found it is mostly used for fraud, bots streaming AI tracks to capture royalty payments rather than real listening.

How much of what people listen to on Deezer comes from its recommendation algorithm?
Aurélien Hérault says roughly 30% of listening on Deezer comes directly from algorithmic recommendation. Most consumption still comes from a listener's own built-up library, and recommendation mainly works as a way to feed new discoveries into that library over time rather than replacing it.

How does Deezer detect AI-generated music, and why is it getting harder?
Deezer's detector looks for mathematical artifacts that generative models leave behind in the audio signal. Hérault says detection keeps getting harder because each time a model is retrained to sound more realistic, its artifacts change, so Deezer built its system to stay resistant to new models without needing constant retraining.

What does Deezer think is the real fix for AI-generated spam in music?
Hérault says better detection alone will not solve the problem, since generative models keep improving and detection is always a step behind. He believes the real fix has to come from changing the music industry's economic model, so that flooding platforms with fraudulent AI tracks stops being profitable in the first place.
