What does "Add to Queue" mean in "Play Music"? What does "Add to Queue" mean in "Play Music"?  I've seen an answer elsewhere which said "it adds to the current play list."  That answer makes no sense.  What "current play list?"  There is no such concept in the application.

For example, I'll start the application and no music is playing yet.  I'll go to my playlists and pick one.  Again, no music is playing yet.  Then I can pick "add to queue."  Nothing happens.  I have no idea what that just did.

I then select a song to start playing, and I'm on my way.  I still have no idea what the "add to queue" accomplished.

I'm using the Samsung S4.
Adding to queue means there should be something playing first before the queue is created. Try playing one song then add another music to the queue. Don't pick another song, just wait for the current song to finish. The next song will be the song you placed in the queue.
