I like to use shuffle, in all off my playlists, but when I'm using Spotify on my iPhone 4S, and I'm shuffelin, but I want to listen to one particular song, I find the song, listen to it, and I'm expecting the shuffle to still be on, like after the song is done, but it's not. I have to go all the way up to shuffle play, every time. This is not OK. What is wrong?! It's working just on all my computers. Help!!
