"Going back to music, studies have shown that one’s musical tastes are fixed by age 30. I think that with effort, one can expand them, but it’s not always easy. Still, I feel sad when I see an educated person listening only to the pop music of their youth".
In my twenties I grew bored with Rock and began a still--ongoing exploration of Jazz. Now in my late 60's, I've been compelled to recognize that my capacity for appreciating unfamiliar music is inherently limited by deeply-ingrained subjective preferences. Now, I spend more time than ever searching for music to buy and I buy less and less. Perhaps this is inevitable. It is also disappointing.
