Proposal

Insert the following text at the end of the "Name" section of Style/Artist.

When adding an artist to the database whose name appears to start with a definite article (eg. "The"), always check whether the definite article is actually part of the artist name. In cases where this is not known, ignore the definite article.

In the case where an existing artist has a credit on a release starting with a definitive article, include the definite article in the join phrase, not in the artist credit.
