A big topic of discussion in music tech right now is active vs passive usage. Active usage is when someone uses a music service or station with the intent of discovering new songs and artists. This mode of consumption values a diverse playlist.<p>On the other hand, passive consumption is when the user just wants background music and doesn't care what's playing as long as it sounds good and matches the mood. This mode tends to favor a more limited playlist, as the overall quality of the music will be higher.
