Spotify's collaborative playlist feature that combines users' tastes is called Blend. It creates a shared playlist based on the listening habits of two or more participants, giving everyone a personalized mix of familiar favorites and new discoveries.
Spotify introduced Blend in 2021 as a way for friends, partners, and family members to compare musical preferences without manually building a playlist track by track. The playlist updates regularly as participants listen, so the results can change over time.
Blend is often confused with Spotify's older Collaborative Playlists, which let multiple users add, remove, and reorder songs directly. Spotify Jam is a separate feature designed for real-time group listening, while Group Session was an earlier name for a similar social listening concept. Blend is specifically about algorithmically combining listening tastes.
