Please have a look at this example:
The big bold title for this recording says:
and was last edited to proper “Faroese caps”.
What is the reason that the two smaller titles («Brynhildur Táttur» on the two release titles «Buch der Balladen») does not have the same capitalization?
In the webservice result for http://musicbrainz.org/ws/2/recording/3cd2b444-3ee6-4ebf-9c90-92778d19400b?fmt=xml you get the version «Brynhildur táttur» (lower case “t” in táttur).
