With Spotify, I am able to connect to my Yamaha audio receiver with from any device (iPhone, iPad, Macbook Air) through my Wifi network. At the bottom of the Spotify app is a prompt to connect to any of these devices. However, with the Amazon Music app, I can only connect to these devices from my iOS Amazon Music app (iPhone or iPad). I can't to find a way to connect to my audio receiver from the Amazon Music software for PC/Mac.
I don't mind connecting to my audio receiver with the iPhone app. But it'd be nice to control music in the family room from the Amazon Music software program too.
