Even songs that break the "rules" of music can be subjectively good, either because they broke the rules or despite it.
Or with cars, a car that's beautiful to one person is the ugliest piece of trash on the street. Some people want a super soft ride where their espresso martini doesn't even vibrate when gunning it through a gravel road and others want to feel every grain of sand on the asphalt in their buttocks. Neither is "correct" and there is no objective measurement for ride comfort.
