It's a big conundrum, I liked reading the poem.

Well written. I think you should write a book on sound alone, you would really be amazing and the book would be really good.

Well thought out. Of course, the fundamental issue you raise, whether sound is particle, is not needed. Sound, a form of energy, is converted to mass by dividing it into the speed of light squared (i.e. the inverse of E=mc2*). The infinitesimal amount of mass created by even the greatest sound imaginable results in, not mass, but entropy. This entropy is by far the most dispiriting of concepts.
