Then don't play music. You are asking for something that only works in a dystopia.
Either the machine tries to understand "what I need now" from partial information and will not play me music when I want to listen because it thinks it "knows what I need".
Or the machine actually is hooked up to my real time health data and possibly brain activity to actually know what I need.
I definitely don't want to have a personal computing machine thinking it knows what I want and deciding for me in such a way, or to have such access to my internal state.
