Diagnose a 25% decrease in song listens on Spotify.

To diagnose a 25% decrease in Spotify song listens, I would first ask clarifying questions to understand the scope and specifics of the drop. Then, I'd brainstorm high-level potential causes, such as technical issues, changes in user behavior, or external factors. I would then systematically investigate these possibilities using a framework like TROPIC (Time, Region, Other products, Platform, Industry, Competition, Cannibalization) to gather relevant data and context. Based on the evidence, I'd form a hypothesis about the most probable cause, test it with further data analysis, and finally propose targeted solutions to address the issue.
