The constructs of album, single and playlist are begging to be expanded on in the space of Apple Music and Spotify. What I want are listening modes. When I listen to a concept album or other work that is intended to be contiguous, I want to consume it that way (and when it is over don't you dare start playing some promoted artist). When I'm exploring some new artist, I want it to shuffle through all of the most popular songs. I want each artist to have an auto playlist that is manually adjustable and expandable to closely related artists. I want genre meta categories so I can tame the genre chaos. I could go on, but the point is that this duopoly isn't driving progress properly because the choice of being on Apple Music vs. Spotify is more about a larger ecosystem choice than features and functionality.
