I listen to music a lot. I might even be described as an audiophile. But I recognize music for what it is: a source of pleasure, relaxation and comfort, and a social glue. I don't feel the need to make pretentious claims -- that by listening to music, I'm learning about the history of humanity, human nature, mathematics, etc. Someone on a carousel might as well claim to be studying physics.
I would never in a million years claim that music is as valuable as philosophy or science. Music simply conveys no truths, except the most trivial truths: about itself, the composer, or (in a limited way) the times he lived in. Whatever Einstein might have said, Mozart is not his equal.
It's all good and well if you use music as a tool for achieving certain beneficial mental states, akin to wine or physical exercise. But spending a large chunk of your time studying classical works, composers, etc. is a horrendous waste of time, unless you are a composer yourself. It's like studying 17-century Russian iconography or the cuisine of medieval France. Pure intellectual masturbation. There are so many unsolved problems in this world that spending your mental energy on things with no practical significance is a criminal waste of intellectual resources.
