Rene Ritchie, writing for iMore, tells you how to set a timer that turns off your music (whether it be a playlist or Beats 1) after a specific amount of time. Excellent if you like to fall asleep listening to music.
Pretty sure this has been around a while, but the ability to fall asleep to Beats 1 is definitely a new angle here.
Now if it were possible to wake to the radio, that would be very nostalgic.
