A big +1 on this. (+10 if I can get away with it

To be clear, since there seem to be different interpretations in this thread about what this means, I am talking about the ability to have "cloud-based" playlists, such that edits to the playlist (song additions, corrections to songs, etc.) are automatically propagated to that playlist on all other user devices. "Cloud-based playlists" should also be shareable with other band members (similar to the list sharing facility in apps like Wunderlist.)

Currently, as noted elsewhere, this requires distributing each change to all devices, adding the revised playlist, and then cleaning up the duplications. Pretty tedious.

Thanks
