I mean, yes. Files as we're speaking of them are in fact this very thing themselves. But:
> Most people are not concerned about files
Do you know how you know that? Is it based off of observation, or is it a story you like to tell yourself?
Like I said, I'm not pulling this out of my nose, I'm basing this off of real life observations including non-technical users. It isn't everyone who wants files in every case, but it is waaay more than a tiny minority. It's a little complicated given that you've got at least two curves you're dealing with (user experience and very roughly speaking intelligence), but if you imagine a bell curve and draw a line about a half standard deviation down from the median, roughly everyone north of that will likely care about files or file-related behavior at some point.
> they want music.
Ask yourself this: do you see "Copy Song Link" with Spotify tracks? What exactly do you think Activities are doing all over iOS?
These are ways of directing/handling files.
> If you do want to handle the raw files then there's nothing stopping you
Except sometimes in applications written/designed by people who think "they want music" means "Most people are not concerned about files."
