Getting "OK Google" to play music from non-downloaded songs in Google Play Music Library? I have many songs uploaded to my Music library on Google Play Music, but don't download more than a few of them to my Google Pixel. 

When I say "Ok Google, play _____", my phone will instead try to play a related station from the app, before stopping and saying that option is for subscribers only, of which I am not. Is there a way to get the Pixel to directly stream it from my Music Library where I've uploaded my owned music via voice command, and not the music station in the app?
I don't Subscribe either and I'm having the same issue. It started about a month ago. Before that OK Google would do exactly as NFG requests:
Me: OK Google, Play Foo Fighters Run
Pixel: Playing Foo Fighters Run
Play Music app opens and Foo Fighters Run plays
