Apple is expanding the availability of its own services on third-party hardware: now it’s Amazon’s Fire TV turn.
Apple Music Streaming with the smart Echo loudspeakers was already possible recently, now the Fire TVs are also available. Here on Apple’s official support page there is even a detailed manual for the setup.
However, it should be noted that Apple’s music service only runs on Amazon devices in the USA. In other parts of the world we still have to wait for an implementation.
