Article Mismatch (Artist)
If you want to check artists to see whether some entries have 'The ' while others don't:
First, define a user library field:
Tools->Options->Manage Library Fields
Add a 'New Field' called ArtistNoArticles and define it as a calculated field:
Now use the smartlist:
[Media Type]=[Audio] ~sort=[Artist] ~nodup=[Artist],[ArtistNoArticles] ~dup=[ArtistNoArticles] ~sort=[ArtistNoArticles],[Artist]
This will display all artists with the same name but mismatched 'The ' article.
