I hope they do get funding so they can support messaging again, one of the reasons I came back to Spotify was for one of my most beloved features. Sending tracks to friends within the application, but then found out it was removed. I still subscribe to Spotify, but the "copy link" send to friend via text is so much worse than being able to just message within.
Yes, I would like to see more social features that aren't tied to Facebook. I know it's not their core competency, but it's odd that the Friends feature requires FB even though they support "standard" non-FB user accounts. And a timeline-esque view of who's been listening to what at-a-glance would be neat.
Maybe it'll scratch your itch, figured I'd share.
