1. Maybe Da Vinci could have done better, even by his own vision, with the Mona Lisa. Maybe you don't like Mona Lisa's smile and if you had your own copy for your personal viewing pleasure, you would change it and that would be your choice. Or, maybe the smile Da Vinci painted was entirely intentional and maybe I want to view it as Da Vinci intended, even if I personally don't like the smile, don't understand why he painted it like that and think that my own judgement is better/preferable. No artist is perfect or creates perfect works but when I view or listen to an artist's work, I want to see or hear that artist's intentions and preferences, not my own.
2. This assertion is false! There is a point in arguing if it sounds as the creator intended, as that affects what the creator intended. Maybe you personally are not interested in what the artist intended, are only interested in your own preferences and therefore there's "no point" for you, which is your personal choice. However, you did not qualify "there is no point" as just your personal choice/preference and therefore implicitly stated "there is no point" for anyone, which is why your assertion is false because there is a point for me and many others!
3. I would state almost the exact opposite! Music is an art form and as such is a form of communication, so as a music lover I want to understand/appreciate what the creator intended to communicate. If I were not a music lover, if instead I just loved satisfying my personal "ear candy" preferences, then you're right and my "focus shouldn't be here in the first place". Of course, some music creators don't exercise the ability of music to communicate and so design their music to be nothing more than "ear candy", which is up to them but clearly this isn't true of the vast majority of music creators or of many music consumers.
4. Sure, you are entirely free to "Enjoy what YOU like" but I'm just as free to appreciate and love music on it's own merits, regardless of my personal preferences (even if I don't like it, or parts of it). For example, I first heard the "Rite of Spring" when I was a young teenager, I didn't just not like it, I actively hated it. It was just an unpleasant sounding cacophony of strained musical instruments. As my understanding of the composer's specific intent and of music composition in general grew, my view of the piece changed. The piece depicts a primitive ritual where a young girl is forced to dance herself to death, which is not a pleasant situation and which the composer communicates by the piece intentionally not sounding pleasant. The overt and subtle specific ways the composer achieves this has changed my view from actively hating it, to it being my most loved piece and I could argue that it's the greatest masterpiece ever composed, even though it's still unpleasant sounding relative to my personal preferences/likes!
1. Now you've heard of another! I always "go out of my way to dictate how people" hear my mixes/music. For example, I will adjust say a guitar part by a few dB here and there. This dictates how people will hear my mixes/music because they cannot deconstruct my mix and change my intention of the relative balance of the guitar part. And again, I am not alone in this, every music producer I've ever heard of does the same, and so do many/most conductors, composers and musicians.
2. No, that is NOT a good example of artists' intent. It's an example of one artist's intent, it's also representative of some other artists but definitely NOT all artists' and probably only a relatively small minority!
