My favorite is, some time around last summer, whenever I told Google to play the latest episode of Wait Wait Don’t Tell Me, it invariably plays some random unrelated (not even a similar name) music on Spotify.
I have no idea if this would work with Google, but I've noticed with Alexa it seems less likely to play a song when I ask for a non-song if I tell it to "listen" to the non-song rather than to "play" the non-song.
