iTunes "songs"

Okay, here's a rant, Apple. More than half of the music I have on my iTunes playlist is not sung, so why do you call it "songs"? One cannot sing instrumental music, for example. Sure, it might only be semantics, but why not call them "titles", or "pieces", or "tracks"? That way you will never be incorrect. As defined by the Oxford dictionary, song is: "A short poem or other set of words set to music or meant to be sung".
