In my opinion, the discourse on subjectivity in music is too predominant to be easily bypassed, because each of us, including professional reviewers, has tastes we must inevitably confront. Sure, one should strive to be objective, but the mere existence of magazines and webzines in the industry (Pop, Rock, Metal; in the latter case, there are even sites focused solely on a branch of heavy metal) shows how pure objectivity cannot be applied to certain contexts. Of course, there are "universally recognized" masterpieces, but how many times do we hear phrases like: "I recognize the importance of the album, but for me...," "Sure, it's a masterpiece, but...," etc.? Based on this, I believe that ratings also reflect this discourse; in fact, those who listen to, breathe, and live Pop will probably give a five to a Lady Gaga or Britney Spears album, ignoring the various Mozarts and Beethovens, whom I consider incomparable to the aforementioned artists for a simple matter of logic—it's like trying to sum apples and oranges; they teach you in elementary school that you can't do that!
In conclusion, I think that discussions like "you can't listen to this or that" lack a solid foundation because it all depends on the context in which one finds themselves. For example, if we enter a hypothetical room where the only 'real' music is Hard Rock, the Classical or Shoegaze listener will be labeled as someone "who knows nothing about music," and the same happens in a myriad of other similar contexts. Ultimately, a crowd listening to a certain genre will always be present, even in the most crude underground! Returning to the hypothetical room: here everyone listens to Drone, a genre that is certainly not commercial, but among all these listeners, there’s one who loves Vasco Rossi; well, in such a paradoxical situation, the latter is the alternative one, and the others are the trend-followers! With this, I conclude by saying that absolutes in the artistic field are truly too little legitimate. Art is in constant movement, and the past has taught us that what is objectively okay today can be judged just as objectively obsolete or even inconsistent and flawed tomorrow. Then, if we enter the realm of opinions, that's a whole different ballgame. There one could say: "For me, you can't listen to Jazz because the only real music is House," which is an opinion and, as such, can be debated, criticized, or shared, but it will always have the dignity of being expressed; this much is certain. I hope I haven't bored you, and good evening to everyone :-)
