Although I have a copy of Spotify on my phone, I never listen on its speaker and seldom through connected headphones. However, I do use the phone as a remote to select and participate in the ongoing stream. I like how every instance of Spotify that is running, is completely synced, the Win 10 app included. I can even yell, "Hey Google, skip" or "Okay Google, favourite that!"
My go-to home speakers are the ones in my Onkyo ATMOS Home Theater System. I usually start via the app on my Nvidia Shield. I could continue on any of the Nest speakers scattered around different rooms here, or through Android Auto in my car. I would love to try joint-listening sessions with friends via the Internet, but I don't have any Spotify friends. 😕
It's a great time for listening to what feels like an unlimited selection of music over wifi or mobile data almost anywhere. It's totally like music that is unchained!
