How do the music and soothing sounds work, and do they turn off automatically?

The music feature plays all ten songs in turn and then repeats, and you can skip a song by pressing the button. Music will automatically shut off 60 minutes after the last button press or speed change. The soothing sounds feature offers five nature sounds — womb sounds, stream, forest, white noise, and distant storm — which play continuously until a different sound is selected or the timer turns the product off.
