The Spofity Mobile Shuffle function works a bit oddly; it’s hard to always know whether it’s on or off. When you’re viewing track information for a song that’s currently playing, tap Shuffle to play songs in a random order. Spotify remembers this setting, even if you exit the playlist and select another one.
But wait! On the iPhone, there’s also a different shuffle button available called Shuffle Play, which appears when you’re viewing a playlist’s contents. If you use Shuffle Play, and then go to a new list, that shuffle function automatically turns off.
On the Android, you also tap Shuffle when viewing track information to randomize tracks from that playlist. Follow these steps to shuffle tracks on Android:
Go to a playlist and tap a track to play it.
Press the I button to open a pop-up window, displaying information from that track.
The Shuffle button appears in the pop-up window.
Tap the Shuffle button, and the Shuffle icon in the button turns green.
The playlist is now has Shuffle turned on. If you go to a different playlist, Shuffle is still on.
To switch off the Shuffle function, tap the I button again and tap the Shuffle button again to deselect it.
