Since the original poster seems to have gotten his layout and structure how he wanted, I'm going to jump into this thread with a couple of my own desires with regards to getting some little artist sorting issues resolved. I don't really like making new threads on forums if I can help it, and the discussion in this topic is close enough to what I'm trying to do that a brand new thread is unnecessary.
To begin, the structure of every track in my library is that the <Sort Artist> value is usually filled with the same value as the <Album Artist> tag. For example...
Nate Dogg <Album Artist>
Nate Dogg <Sort Artist>
G-Funk Classics, Volume 1 <Album>
For the entire album, the <Artist> tag is also entirely filled by Nate Dogg, so this is a perfect case scenario. I do not use the <Sort Artist> tag for "Last name, First name" information. (Yet - I haven't begun to move my entire classical library into MusicBee, so this might change.) Waaaay back in the day, when I first started seriously tagging my music collection, I put the soundtrack or score title in <Artist>, then moved them to <Album Artist> a little less back in the day, but still long ago. I moved the titles to <Sort Artist> and opened up <Album Artist> for me to associate my tags better with Last.fm for the future scrobbles.
Anyway, other than using <Sort Artist> "incorrectly," for what I'm doing, the tag works great except in one case - multiple artists. For example, my artist tags for the album "Together" from Marvin Gaye and Mary Wells are...
Marvin Gaye <Artist>
Mary Wells <Artist>
Marvin Gaye & Mary Wells <Album Artist>
Marvin Gaye <Sort Artist>
Mary Wells <Sort Artist>
The way this works for the most part is great, 'cause when I click "Mary Wells" on the main panel, I can see all her albums... plus the one she shares with Gaye, and this also works vice versa. However, this also has the unfortunate little side effect of each track in the album "Together" displaying twice whenever the entire library or "M" artists are displayed on the main panel (which, by the way is sorted by "Sort Artist.") When just "Mary Wells" or "Marvin Gaye" alone are selected, however, the number of tracks in all albums displays just fine. I've played around with different settings for about a week now to remedy this and so far... nothing.
The second little issue I'm trying to work around is on my "Soundtracks" panel, which I currently have sorted by Virtual Tag $Sort("("<Year>)) <Album> and grouped by "Sort Artist." What this displays is the following...
Marvel Cinematic Universe
(2008) Iron Man
(2008) The Incredible Hulk
(2010) Iron Man 2
...
...
What I want it to look like is this...
Marvel Cinematic Universe
Iron Man
The Incredible Hulk
Iron Man 2
...
...
Any thoughts or suggestions on achieving this? (EDIT: I'm trying to get this look in the Thumbnail Browser, where I don't have the option to use a Custom sorting method.)
