The boosted customer engagement Challenge
In early 2026, Deezer, the global music streaming platform serving over 16 million active users worldwide, faced a critical engagement crisis. Despite having an extensive catalog of 90+ million tracks and a sophisticated music discovery engine, user engagement metrics were declining steadily. Monthly active users were spending 23% less time on the platform compared to the previous year, with average session durations dropping from 47 minutes to just 36 minutes. The skip rate had increased to 68%, indicating users weren’t connecting with recommended content, and playlist completion rates had fallen to an alarming 34%.
Boosted Customer Engagement: Table of Contents
The core issue stemmed from Deezer’s traditional recommendation system, which relied heavily on collaborative filtering and basic demographic data. This boosted customer engagement approach failed to capture the nuanced listening patterns and emotional contexts that drive music consumption. Users were receiving generic recommendations that didn’t align with their mood, activity, or evolving musical preferences. The platform’s inability to understand real-time user context meant that a user exercising at the gym might receive slow ballads, while someone seeking focus music for work would get high-energy dance tracks. Additionally, Deezer’s content discovery mechanism wasn’t effectively surfacing emerging artists or niche genres that could expand users’ musical horizons, leading to a stagnant and predictable listening experience that drove users toward competitors like Spotify and Apple Music.
