Spotify AI DJ: Personalized Music Curation at 600M-User Scale
The Problem
Spotify had over 100 million tracks but users reported 'decision fatigue' in choosing what to listen to. Existing playlist algorithms surfaced familiar content and struggled to introduce new artists in a contextually relevant way.
The Solution
Launched AI DJ in February 2023 — a personalized curation system combining Spotify's recommendation algorithms with generative AI commentary. The AI DJ provides spoken context about songs and transitions using a synthesized voice modeled on real DJs.
The Outcome
AI DJ became one of Spotify's most-used features within weeks of launch. Measurably increased discovery of new artists among users who engaged with the feature. Demonstrated that AI narration increases engagement with recommended content.
Key Metrics
- One of Spotify's most-used features post-launch
- Increased new artist discovery by measurable margins
- Expanded to 50+ markets within 6 months
- Used by tens of millions of users
