I had been using the Google Play Music app to play all of the songs on my phone in alphabetical order, as a way of going through them all and deleting the least worthy to regain some storage space. I had reached the 'C's. Then I had occasion to go to shuffle mode in a social situation. Now I want to get back to weeding out my library, and I can't figure out how I got it to play everything in alphabetical order. I clear the queue, and from the Songs tab tap on a song, it begins playing that song but also adds every song on the device to the queue in shuffled order. I clear the queue, and from the Songs tab bring up the menu on a song and select Add to queue, and it puts just that one song in the queue and plays it - but hitting next track just restarts that one song since it's the only thing in the queue. What I seem to need is from Songs "Add all to queue, in this order" but that doesn't exist. I wonder how I did it last time. That "Shuffle all" in the menu does not appear to be a toggle - it immediately adds everything to the queue.
