It is generally true that listening is subjective, because knowing a bit about the physics of sound is not an everyday skill.
But there are formal and objective studies which can equip the ear to be very objective. Music theory is one branch. Audio acoustic engineering another.
And all listeners are dependent on a healthy set of ears. I have found that many seemingly dull listeners actually have hearing impairments and are not hearing all of what is present.
Probably the most common taste that I’ve noticed among the untrained, is the love of good bass response. If it thumps, it is good for them.
