Why are these devices connecting to the Internet at all? Aren't they supposed to be connected to phones and TVs via cable or bluetooth? I would never allow any "smart" anything device to speak to the Internet in the first place.
They can play Spotify and radio over the internet.
You used to be able to walk over to a speaker and with 1 button click play music from a preset on a music service like Tunein or spotify.
Now will need to fiddle with your phone to connect with bluetooth or something.
