How does Spotify Connect works? (I mean in technical details)
For those who don't know Spotify Connect I'm explaining it. Spotify Connect is a feature integrated in the Spotify App (iOS, Android, desktop... whatever) that allows you to play music in compatible speakers, like Sonos for example. When you add the Spotify skill to your Echo device it become a compatible speaker for Spotify Connect, so if you are playing music in Spotify in your computer you can select your Echo device from your computer to continue the streaming of the music in your Echo device without saying "alexa open spotify" or whatever.
How is it possible? I mean I can't make my Echo device do anything without saying "Alexa, ..."
I hope what I say make sense to you all.
Thank you.
