I believe I'm correct in saying that usage eventually determines meaning. Anyone who is around people 25 years old or less knows that for virtually everyone in that group "song" means any musical composition whether sung or not. If it is already not defined that way in some dictionaries I have little doubt that within a few years it will be.
I can't help agreeing with you.
I agree totally. While I'm with those who would sort of like
"song" to be reserved for how we use it, we're fighting a losing battle. And really, there isn't much point to the battle. I think if anything, we should be glad that more and more people, including those not more heavily immersed in classical music training, are interested in classical music, including to the point of participating in a forum such as this. And language evolves. I'm sure there are hundreds of words and phrases that all of us pedants use, without a second thought, which were originally 'misuses.'
Speaking of which, there's another current 'misuse' which I would bet 99% of us pedants now use without a second thought, which bothers me a lot more than this song thing. In fact, I might even be the only one who considers it a misuse
but that's my story and I'm sticking to it:
"Shipping," when no boat is involved.
I cringe a little every time I see the term. I call it "delivery." How it got to be "shipping," I don't know. But it is what it is.
