Imagine a user listening to a podcast (actually any podcast) for 10 minutes and then never again for 12 months. What does that tell you?
A. They liked that podcast (any podcast actually) so much that they want it to be the very first thing they see when they open Spotify for the rest of their lives.
B. They don't care at all about that podcast (any podcast actually) and at some point might get so annoyed about getting it shoved into their face over and over again that they seriously consider canceling their subscription.
Choose wisely.
