I would like to be able to share information about recently added or played albums/tracks in human- and machine-readable forms directly, rather than having to add manually to a playlist and then export the playlist as XLS.
Agreed, sharing playlists is a requirement today.
I do see the difficulty in this as each album/song must be identified uniquely and at the same time be publicly available.
Then it will not matter if individual objects can be matched to the target user/systems local library or any available online streaming service.
Not sure these rants make any sense though, it’s a difficult subject.
I like the concept of shareable playlists - after all, music is far from a solo pursuit & the sharing of playlists is common practice.
