Okay, so you can't stand to hear some 10 year old kid play the g minor ballade with a perfect tone and all technical parts played with a good technique? A teacher can tell him some musical details so that he might be able to 'feel' the music a bit more, too. If you can't see that as a good and satisfying performance, I pity you.
I pray to God that I misunderstand all the things you said here, but this is how I understood it:
You can't stand listening to an example as the one above, but has to listen to a full developed artist, who is (most possible) extremely depressed (probably on the edge of suicide), while he is happy as can be, lost half of his family in the war, while he found his true love (who he most probably met in the most romantic way possible), aaand being still alive? Again, I feel sorry for you that the only artists you might find slightly worth listening to probably are dead, and probably never even lived.
And how about taste? Chopin's music is often very very sad, but still almost always have this sort of pride in it, while Liszt's music sometimes goes faaaar beyond that. Bach's music was studies, and Mozart never really felt he way his music suggests. How is one person able to have lived through all that?
They don't, they listen to how they sound, and change it if they don't like it.
