No that doesn't work. Saying, "Alexa, play Jack Radio" causes her to ask, "What do you want to hear." Which in turns causes me to reply, "I just told you what I want to hear you stupid $%^&%$#!" I think Alexa needs to be better programmed. Before I set Pandora to the default music source, Alexa could not find the Pandora stations I had created. After I set Pandora to the default music source, Alexa can find them but I definitely have to add "on Pandora" or she gets confused.

BTW, I still have not been able to get my Echo or Dot to play my Unlimited Amazon music plan. Seriously Bezos, just bite me!
