create playlists with friends

This would be soo unsefull. I'm trying to set up a playlist for this years road trip, but sometimes in someone finds it he can add songs to it (collaborative playlist). This is really annoying and it would be so useful to only let certain people edit the playlist.

How is this not a basic feature?!

​@flabes have you tried Shaker?

Shaker does not let you edit the playlist picture, and is missing from the PC desktop app. It would be really great if we could edit normal playlists with a friend.

The same here.

I would like to set up a private playlist, that i can collaborate with my family, but no one else. 
it should stay private.

We are looking for something to leave Apple Music, but like this it is not possible.
