Preferences in music have to do with the listener, not the music listened to. There is only what your reflection tells you, not the projected image itself. The definition is inconstant, as it cannot be defined, only averaged.
In this place called reality, this holographic dimensional space, objectivity cannot exist, and does not, by all scientific measure. Objectivity is a subjective mindset, nothing more. Music, by that fundamental reference, is purely a subjective and personal reflection, and is never about the music itself, and only about the listener.
