My "Friend Feed" is back on all of my 1.0.nnn versions--
Thank you Spotify!
Yeah, this sucks. I frequently swapped music over this functionality. I don't do any of the social media stuff, so no sharing there. Hopefully something else will come about.
Being notified when my favorite bands release new music was my favorite feature. If any of the competition still has that feature I think I may have to switch over. It's a shame, I've been using Spotify since the day it launched in the US.
