As a Sabaton fan, I laughed out loud. Technically they have classic music sounding (roughly) songs, e.g. Christmas Truce, but yeah, that's a massive fail.
"Play music on dining room speaker." (dining room speaker starts blaring music at high volume) "Turn down dining room speaker." (No response) "HEY, GOOGLE. Stop music on dining room speaker." (dining room speaker music volume decreases) (from the dining room speaker) "Can't find dining room speaker." (dining room speaker volume increases, blaring music)
I did follow the advice here to rename all my speakers lowercase, since google home's VOICE interface seems case-sensitive:

And since the Google Home android app is, literally, the worst and least-reliable mobile application I've ever used, the voice interface is pretty much all I've got.
Then Siri had the gall to claim NO MUSIC WAS PLAYING as this super loud music was assaulting our eardrums. My wife thought my exasperated struggles were the funniest thing, it felt like HAL-9000 with the “I’m sorry I can’t do that Dave” moment.
