The Amazon Echo is a Bluetooth Receiver

Lost in the shuffle of the Amazon Echo Dot that we’ve been using for the past month is its capacity to receive as well as send via Bluetooth.

I knew you could pipe the audio from the Echo into a Bluetooth speaker; what I only realized today is that you can pipe the audio of other services—like a phone or tablet—to the Echo.

For me this solves the problem of there being no SoundCloud skill for the Echo: I can simply use the Android SoundCloud app and send the audio to the Echo. Because the Echo is hardwired to our hifi, this gives me a handy bridge to blasting SoundCloud audio into the living room.
