Upon my arrival, we observed significant insights regarding social features. Traditional social elements like an activity feed and messaging were found to lack strong engagement and were perceived as catering primarily to power users. In contrast, users with existing social connections on the platform exhibited higher engagement and retention metrics. These insights crystallized into our guiding principle, termed "Social as a layer." This concept aimed to conceptualize social not as a separate destination within the app but as an ambient, ever-present element—evoking a sense of connection with familiar individuals and their relationship to music. This philosophy seamlessly aligned with Spotify's overarching goal of providing music for every moment, catering to a broader audience, including more casual users.
