I'm going to go out on a limb here and suggest that some of the differences we have in our musical tastes may stem from philosophical differences.
WARNING!!!! THIS POST CONTAINS OPINIONS AND SHOULD NOT BE CONSIDERED TO BE ABSOLUTE TRUTH!!! VIEWS EXPRESSED ARE THE SIMPLISTIC STATEMENTS OF ONE INDIVIDUAL'S THOUGHTS AND SHOULD NOT BE CONSTRUED AS AN INTELLIGENT PHILOSOPHICAL DISCOURSE!!! WARNING!!!
If one has a philosophy of life that views reality as ordered, structured, and embued with meaning, one will have a tendancy to reflect this in their artistry. If one views order and chaos as opposing forces, this will be shown in their art. If one views reality as ultimately chaotic and random, one will display this view in their artwork.
We look, consciously or not, at life through lenses predisposed to see what we expect to see. If this process is unconscious, we may not be aware of our assumptions and their impact on our art. As we examine ourselves and our philosophical assumptions, we may choose to change our viewpoint and embrace a new way of life and a new artistic sensability as a result. If we have consciously thought this through, we may already know why we view life, the arts, reality, etc. in the way we do and may feel no need to agonize over it any longer.
At any rate, our views, our art, and our tastes are ours alone. Others may have similar views and opinions, but not always. When someone does not share our views, we can choose to view the person as "less enlightened" than ourselves, or we can accept that they are living out their philosophy. They may change their view at some point. We might change ours as well. In seeking to understand someone's tastes or their art, it may be helpful to understand their philosophy of life. It doesn't mean we'll agree and adopt the same philosophies, but at least we can work towards understanding.
