Unfortunately, there is currently no plugin for the Squeezebox Server to support Amazon Prime. People are constantly requesting it from Amazon, but they are not that keen on supporting third-party open-source solutions. However, there is a work around to play your Prime music under Max2Play’s new Bluetooth plugin (beta updated)! You can now couple your phone or tablet with a Pi and then create a “radio channel” in the Squeezebox Server that play the output of this Bluetooth device. This way, you can feed your phone or tablet’s Amazon Prime music playback to all your Squeezebox players through the server’s channel.
The steps to make this happen are very easy and are explained in the Bluetooth plugin’s description. Check it out!
