What I have done is open the Apple Music app on my iPhone. scroll through whatever I want, hit the plus + on whatever I want, goes into my playlist. Then when I go to Apple Music on the Apple 4K-TV when I am home and hit my playlist and everything is there.
For instance, I have the entire Spatial Audio play mixes, Rock and Jazz on my playlist, so as they change I am always up to date. In other genres or whole albums I pick and choose, but it is the same process.
I of course can do it with the remote at home, I just find using the iPhone for organizing much easier.
