Some solid suggestions from Kirk McElhearn. I hope Apple reads posts like this, really considers some of the pain points. I’d also suggest that Apple spend some quality time with SoundShare (see Point #3). Collaborative playlists is one strong feature of SoundShare, but there’s much more to it. The app has social in its bones, and social is something that Apple Music has traditionally struggled with.

Why not bring the developer in for a meet-and-greet with the Apple Music team, preview planned Apple Music APIs, see if the SoundShare team have suggestions to make things better for both sides.
