I've downloaded Spotify on my laptop and it works excellent. I do realize using the free app on an android phone requires using shuffle play. However, I can choose a song to play and pause it, but can't get the shuffle play to work. In fact, I can't change the song that is playing in my playlist unless I pause the song, click on different category in my playlist, and click a song directly. Shuffle play is lit green, but will not work. Android version is 4.4.4 and it is a Samsung Galaxy S5.
