You've discovered an exciting song, but don't want to interrupt what you are listening to right now? No problem! That's what the queue is for.
Just tap the three dots next to the item (song, album, etc.) you want to listen to next and select "Queue". From now on, everything will be automatic.
You've queued up several items and want to see what's next? Easy! Go to the player view of the current song, tap on the queue icon in the lower left corner and you'll get into the queue.
Here you can see at a glance what is currently playing ("Now Playing") and what will play after ("Coming Up").
Have fun discovering and listening!
