song's artist name is on the image, do I put artist name tag

so basically normally artist name would be used as a signature/artist who drew the art, in this scenario the art is a fanart of a certain song with both the song name and the song's artist name on it, do I put the tag artist_name on it?

That's what the artist_name_(singer) and creator_name tags are for. Edit: Also this would be better posted in topic #12251 next time.
