We've made the move away from Spotify. It's something we've discussed a few times but I've never got my act together to do anything about it. Tidal works just fine with Android Audio, and everyone in the household is happy with the available music (almost no different to spotify, so far), features, and quality.
Cancelling the premium family account with Spotify could have been easier, they really try to talk you out of it. And I can't find any way to remove the payment method!
