I just signed up for Spotify via Facebook.  It seems to show me everything fine, artists, celebrities I can follow, apps, except for Facebook friends.

I have Spotify exempted from the only firewall I use.  It just doesn't show any possible Followers from Facebook.  It only says:

Facebook Friends on Spotify: There are no more people to show at this time.

I've signed out and signed back in several times, the problem is persisting.

**Update**

A friend managed to link me to music, which linked me to her profile.  Facebook friends are still not being shown.
