Collaborative Playlist and Sharing Songs

[oblioness]

Spotify, I hope you can share a solution to this problem before there is a mass Exodus from your service. 

Me and a whole cluster of my DJ friends have used Spotify to collaborate on music. Now that you have removed the messaging feature to share songs WITHIN Spotify, inclusing collaborative playlist, most of reason for paying for Spotify has ended.

Here are the issues we need addressed or we are all leaving:
How to work together in collaborative playlists?
How to  share things within the Spotify app, not outside?
