I see Spotify is pushing updates for their mobile app... some are laggy and aren't as optimized. They make a few tweaks here and there, but I wish there was an option to play next ( next to the add to queue button) it'd be nice to have that, and also the app isn't as fluid as it used to be on my device (also takes longer to load), and I have having a song removed from my Playlist when I hit the unlike button by mistake (through the notification panel).
