Being a fan of "classical" music myself, I can tell you establishing a commonly-accepted word for it is hopeless. We know that there are two senses of the word; the strict sense which refers to Mozart et al, and the general sense which covers music from Josquin des Pres to Philip Glass, but with notable exclusions. You can't even get agreement on what constitutes classical music in the broad sense. Does it include Scott Joplin? J.P. Souza? Paul Simon? Stephen Foster? If not, why not? Until music lovers can get general agreement on what is and is not classical music in the broad sense, you can't expect to agree on a label for it.
