Amazon has added the ability to designate a sleep timer when adding music playback to an Alexa Routine. It’s a simple change, but one that many people have been wanting for some time. When adding music to an Alexa Routine, in addition to specifying what music should be played and from which music service, there is now a third optional option to set a sleep timer. Oddly, Amazon has limited what specific timer duration can be set by only letting customers choose from 0-4 hours and minute quantities of 5, 10, 15, 30, and 45 minutes. Hours and minutes can both be set independently, so you can set a timer for 2 hours and 15 minutes, but you can’t exceed 4 hours or set an arbitrary number of minutes.
