Why does my Aurender only play one song and then stop?

If your Aurender is just playing one song at a time and then stopping, it is most likely that you have accidentally engaged "single play" mode:

"Single Play" mode was developed by request from some of our dealers and exhibitors so that they can say a few words to introduce the next track before it starts playing in a live demo.

Most users will not want to use "Single Play" mode at home. 

To disengage it, tap the "S" icon to toggle through various repeat modes until the desired setting ("repeat off", "repeat single track" or "repeat queue") is engaged.
