Implementation of Music Service Recommendation System
Music recommendations — one of technically most mature domains: Spotify Discover Weekly, Apple Music Radio, Last.fm — each has its architecture. Specifics: session context ("mood"), discrete events (skip after 10 seconds = dislike), audio features as supplement to behavioral data.
Session-Aware Music Recommendations
Spotify Discover Weekly achieves 30% likes (heart button) — excellent indicator for new content recommendations. Key metrics: long-term retention (users after 6 months), skip rate in first 30 seconds, diversity score (genre diversity), serendipity (content discovery outside usual taste).
