Same here. On the other hand I think it is just how some people are. I do not appreciate art, and can live happily without music. Art in general, never gives me any profound experiences. Books on the other hand, now we're talking! Political performance art, also entertaining.
Idk if you ever shared this view with art people. It must have been hard because there is a sort of obligatory necessity that people MUST like art embedded into their worldview.
But also, there is a basic universality of art, and I wonder where it comes from, and what would make some people into it, and others, like you, not into it.
