I have 5 different google speakers: kitchen nest hub, fireplace speaker, sunroom speaker, bedroom node, and upstairs hallway node. I have created a group of three speakers containing the kitchen, fireplace, and sunroom. I also have my own MP3s/M4a's of songs I copied from old CDs, and I'd like to hear some of those music files on my various Google speakers. So how do I do that? I was going to upload music to Youtube Music, but apparently that's not what YouTube Music uploads is for. (At the very least, I wasn't able to get it done.)
I don't subscribe to Apple's Music or Google or Spotify or any other such service. So how do I broadcast the recordings through my speaker/speaker groups? There's got to be a way, but I'm not finding instructions for doing it online.
