That’s the dream, but we aren’t quite there yet. You are describing a Routine, but right now only step 1 can be added to an Alexa routine. I don’t use amazon music, but at this point I think you are stuck with “Alexa, turn on receiver” then “Alexa, play jazz everywhere”. I do this with my setup using Spotify or Sirius XM, but I do have to specify the playlist or station i want.
