Pretty sure lot of people have been wondering or asking about a native app for Android/Google TV. Given that nothing native exists (not that I know of) it would make sense to beat the competition (including Apple at this rate). Is it something that requires a lot of work? Cider on Windows runs circles around Apple Music for Windows and let's not even mention iTunes for Windows.
p.s The same goes for all the other OSes out there (not tvOS obviously).
