I've seen two topics of this before, but with no solution.

I am a Spotify Premium subscriber. I have turned off autoplay in my Spotify app.

I keep telling my Google Home Mini to play a <song title> and the <artist> but it just keeps playing the song radio and not the specific song, which in turn plays some random song on the radio.

I've even resorted to saying "hey google play <song title> song by <artist> and NOT the song radio" but of course it still keeps playing the song radio and not the specific song itself.

What is happening? How do you fix this? It is extremely annoying and makes my Google Home Mini useless!
