Music is something that happens in your mind. The stimulus need not be a sound. A written score does not need to be played to be understood as music. A sound designer/editor can look at a waveform and see the music. A profoundly deaf person can feel music.
The majority of people on this planet do not need audiophile quality sound to enjoy reproduced music. Even when exposed to audiophile quality sound reproduction the majority of people are not converted. Musicians famously do not require audiophile sound. Only audiophiles need audiophile quality sound, hence they are listening to their systems. And there's nothing wrong with that.
