This is kind of irrelevant in the long run. If you're so popular people will want to use your music and you deny it, it'll just copied (or used anyway, as most of us aren't keen on fighting legal battles or, worse, we can't KNOW of many of the possible infringements as they're on someone's 5 subscriber youtube channel.) If you can even stop people from using your music or sharing it, that is.
We don't live in a time where any of this matters anymore. If your music is out there, it's out of your hands and whatever happens to it, happens. If you can't accept this, then you better never release any music (or why even bother composing as it could all potentially leak out into the wild!?)
The only way to ensure control over your music is to not share it with anyone, so it is with culture in general (or as said previously, just don't bother composing if you care that much.)
