It would be useful to have some additional collaberation features, specifically the ability for the author to have a list of all changes made my users, and roll the playlist back to a certain date/time if its been changed, or tracks were maliciously deleted. It would save constantly having an additonal 'Backup' playlist in my sidebar.
The ability to block users, approve tracks or only allow certain friends to edit the playlist while it still being availible for the publicly would also be VERY useful, however I think that has already been suggested a few times. It would be nice if you could manually credit someone else with adding a track (say if it was removed/re added to a different playlist) which could then it comes up as a notification for the user. Similar to when you are tagged in a photo on Facebook.
Collaborative playlists are a great featue, but they are very basic and haven't changed much/at all since they were first implemented. If you search the web people have been requesting things like this for years!

Make Spotify better with social features
1. Playlist ratings
Rate them 1-5 stars - I'd love to get specific playlists emailed to me on a recommendations basis and rate them. Spotify can then populate these playlists, by ratings. ie: "View Top Rated user playlists" by genre.
2. Like song within playlist and alert owner
My friends and I share playlists. I'd like to "Like" a specific song within their list and have Spotify notify them.
3. Find friends by email
I have disconnected my Spotify from Facebook (which was a huge ordeal BTW). I'd like to search for friends by email.
4. Custom profile and picture
I am not attached to Facebook, and therefore cannot add a profile picture. I'd also like to have an "About Me"
5. Featured user playlists
I'd like to be sent featured user playlists based on my music taste. I'd also like to be featured! :)
