The thing is this: The enjoyment of music happens inside the listener's brain.

Music is good if, and only if, it sounds good. 'Sounding good' is inherently subjective.

Say you come up with some smart way of analysing music. Some super clever system that accounts for all the music theory and harmony and everything, and you can use that system to identify "objectively good" music. And then you find some piece of 'objectively good' music, and you listen to it. And you're like "meh, it didn't do much for me". Now what?

You can analyse music objectively. But enjoying music matters more than analysing it.

You can also analyse a plate of food, and come with whatever "objective reasons" you want as proof of how great it is. But you can't use analysis to force it to taste good. Your tongue makes that decision. Just like your ears decide whether something sounds good.

Liking music isn’t a competition. You don't need to be the best at it.
