The problem with this bullshit mentality is that no one defines any terms anymore. Everything is subjective when nothing is agreed upon.
However if we take the time to fucking set some parameters of what we like in music, what is enjoyable, what things are praiseworthy and what things are cringy, then we can definitely say some things are better than others. If we agree that complexity is a characteristic of good music, we can agree that Twinkle Twinkle little Star is not as "good" as Miles Davis' So What. If we agree that lyrical complexity is good, we can agree that Aesop Rock is better than Lil Pump. So on and so on
