No, we are not animals for one very strong reason: we have the capacity to rise beyond living pointlessly for survival and reproduction.
Freiderich Neitzsche claims in Beyond Good and Evil that all feelings are mere chemical reactions, and therefore irrelevant; while this is undoubtably true, what Neitszche failed to recognize is the importance of it all lies in
why these chemicals are released. The same applies to this--pleasure, of course, is a bodily-chemical reaction; one must therefore examine the reasons behind the chemical release. Music does not generate this same release of chemicals; there is no physical pleasure, only a
psychological uplifting . This, too, is obviously caused by chemicals, but again that is irrelevant. The difference in the feelings lies in the fact that we are genetically predisposed towards having that uplifting, that calmness, that wonder occurr at the time of hearing music played--and quite admittedly, there is no reason that this should alter one's chances of survival or reproduction. So why then do we feel this sudden change in emotion?
Because hearing music puts us in touch with reality, with the present moment. It briefly centers us, letting us bask in the contrast of harshness and beauty, briefness and eternity--the Numinous. Music flows like a river, always in the present. The truth inherent in either its lyrics, notes, or rhythm is a manisfestation of the Absolute.
I'll answer your questions in the morning; right now I'm exhausted (having had birthday celebrations all day
