I have YouTube Music as my default service for music in Google Assistant. Years ago, I was able to ask GA to play cuts "from my YouTube Music Library" but that isn't possible anymore. Is there any current way to make GA play uploaded music by calling for the artist or playlist? I have uploaded the artist's songs, and have created a playlist for this <artist>. When I ask GA to play <artist> "from my library" or "from my playlist" I always get the reply, "OK check out this <artist> station" and *no surprise* it isn't that artist at all. Can anyone get uploaded YouTube Music to play using verbal commands?
