Dear Spotify: I never EVER post on community message boards. However, I felt inclined to because I use Spotify A LOT. I also use Spotify exclusively on my iPhone and I'm sure a lot of people do as well. Please make it capable for users to share (in app via inbox) playlists with other Spotify users. Sharing capabilities via mobile only allow sharing via Facebook, Twitter, Email or by SMS. Users should be able to share by looking up other users who we are following. I've posted this same issue on a Spotify review for iTunes. I gave 1 star only because of this reason.... PLEASE FIX. Thanks!
