Seems a good solution to me. In popular music, in general, you always
thought in the performer and the composer (creator) is not relevant but in
classical is almost the opposite. So in classical you probably have both,
performer and creator, but in popular music only the performer.

With your solution there is always the same information available,
performer, and creators is only available when have performer too.
