Tried logging in on my Samsung TV spotify app, (newly installed) but it says I need Spotify Premium, is that true? Even though I can now (with Spotify's new policy) get spotify for free on my phone and ipod etc on the same wireless network. I could probably just mirror it from the phone onto the TV but it seems pointless when the TV has the app.
Yes, all hardware partner devices require premium. Free is only available on desktops/laptops, android and ios.
