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.
