Have a playlist/folder with each years favorite music from 2010 up till 2017 and I usually just go into the playlist and choose "play all" at the top, and it'll just play/shuffel all of the songs inside playlist 2010 through 2017.
When I was going to do this now the "play all" button at the top wasn't there any more? Why on earth would you remove something like that? Why!?
It's still there on the computer version of Spotify so why have you removed it from the iOS and probably Android app? This is a major step backwards Spotify!
Please bring it back pronto!
