Redesign of Google Assistant Conversational Flow for Music

I tried to play a song on my phone through google. Even though it was available on spotify and apple music, google assistant only let me play it on Google Play and asked me to subscribe to it.

If Siri and Alexa can play from Spotify, why can't Google?

There are many things that are wrong with this - by only allowing its assistant to interface with it's own products, Google is indulging in anti competitive behaviour, unfairly privileging its own apps over others.

So I have proposed a redesign of this conversational interaction where the assistant instead of rudely and disrespectfully forcing you to subscribe to it's own services, helps you by showing you where else your request is available.

Do let me know what you think!
