For example, take http://musicbrainz.org/release/f0d155f1-4769-4e1f-bb7a-2b7be9c8a8a0?tport=8000

At time of writing both tracks and recordings are credited to "JAY-Z & Kanye West" using artist credits. I have enabled "standardized" for everything; so the artist credits in Picard are being taken from the recordings, which is fine... except when I have "Standardize artists" enabled; I think I'd expect that it'd use the name of the artist, not any "credited as" - from either the track or the recording. At time of writing the actual artist is credited as "Jay-Z" without all caps. Long story short, I'd expect Picard to standardize these credits to "Jay-Z & Kanye West" based on the actual artist entries.

However, nowhere in the web service response does MB return what the /actual/ artist name is; only the credits - so I understand why Picard is not doing this. For a VA release, or releases with lots of artist credits and thus different artists, it'd be untenable for Picard to make an artist/mbid request for every artist.

I've attached saved XML from the WS to capture state of the artist and recordings at this time (there are JAY-Z vs. Jay-Z edit wars gwarn' )
