Although I would appreciate recommendation feed that's private I know that's impossible.
I basically download songs anytime I get a recommendation or hear it somewhere. I usually listen for a while or add to a playlist. Very simple use case.
Private means I know and things I choose know what I listen to and others don't. I would also preferably like ownership of my music. I would consider not private something that uses my data for anything except necessities(no algo no selling)
