As Sarastro has already pointed out, you don't seem to have a clear understanding of the term "philosophy", und that makes your statements somewhat messy. "Philosophy" is not - as you seem to imply in your last post - a bundle of unconscious aesthetic or ethic values, but a process of consciously checking the validity and cogency of arguments and theories. Philosophers have thought a lot about music, what you can see if you read Plato (Republic), or Kierkegaard (Either-Or), or Schopenhauer (The World as Will and Representation) and Nietzsche (The Birth of the Tragedy) and various writings of Adorno. On the other hand, some composers have also been influenced by the philosophers of their time to a certain degree (but perhaps not as strongly as the other way around, and it would be difficult to locate these influences in their music). This would indeed be an interesting topic, but probably too extensive to be discussed here.
And now it comes to my mind that there are even some men who were both philosophers and composers: Rousseau, Nietzsche, and Adorno.
If you really want to learn more about the contemporary philosophy of music, I recommend to start by reading the following article in the Stanford Encyclopedia of Philosophy, which is really up-to-date:
