ALBUMARTIST & ALBUM ARTIST conflict

[Rufus McDufus]

Thank Simon! What happened is that I've been altering some album artists to be a single value , where previously I used multiple album artists (i.e Tom Petty & The Heartbreakers where previously I used Tom Petty; The Heartbreakers). I've done this in Mediamonkey which appears to be changing ALBUMARTIST correctly but for some reason I'm ending up with a mixture of old and new values for ALBUM ARTIST (even though MM doesn't even edit this as far as I can tell, and there's no way of editing this extended tag in MM even if you wanted to). So ALBUMARTIST is consistent & correct across a whole album but ALBUM ARTIST is not. The whole album doesn't seem to get indexed under ALBUMARTIST for some reason.
I've been fixing the extended tags in mp3tag and all is good, but it was a bit baffling. The issue seems to be with Mediamonkey but I wasn't sure why they werent getting indexed at all in Minimserver.
