Usually the way this works is that there's one guy who starts making songs to put on YouTube and gives them a (hopefully) amusing artist name. I usually sort this out by putting the amusing name on the song page, but link it to an artist page that uses his actual name - especially if other places on the net do this. Apple Music credits Steven Gary. That sort of thing.

It's not a necessity now (especially with so many exceptions in the archive), but if he makes anything newer that's credited differently, I'll do the whole "separate credits" thing. Just remind me if it happens.
