So I don't know if any of you are having any the same issues, but I personally have found that without a YouTube Premium account, not only am I unable to stream my own music
to my Smartspeaker, but I am also unable to stream any of my music
to my car
speakers
via Bluetooth.
Personally I am getting more and more ticked off at Google for basically Forcing me into having to purchase a YouTube Premium subscription if I ever hope to listen to any of my music using anything else other than the built-in speakers
on my phone
