If an album contains tracks with different date value like compilation albums, current MB's display of the album gets messy and inconsistent.
In Artwork view grouped by album artist, sort by album ascendant:
In Artwork view grouped by album, sort by album artist/year/album:
In Album & Tracks view, sort by album artist/year/album:
As you see from the above, (1) album year is inconsistent depending on layout (but with basically the same sort criterion) and (2) track list is out of order even though those tracks belong to the same album.
Then how to fix this?
Someone might argue the tagging was wrong. Those tracks should have used the same "release date" (2011) for date tag, and the currently entered date tag values should be moved to "original date" custom tag. Maybe theoretically that's a correct approach, but then it raises other issues. Do you really want to tag for The Beatles's "Please Please Me" dated in 2012 simply because your compilation album was released in that year, while hiding more important date "1963" in an obscure custom tag? And the chances are you will end up with having the same song in several different date version. Also, most features and panels in MB shows date, and displaying a custom tag instead is not allowed in many cases. In some genres (like classical music), album release date is not that important as compared to track release (or recording) date to make it worthwhile to re-tag the whole library under a new system.
So what I'd like to suggest is to add a new MB internal field "Album Release Date" for album-sorting purpose only. Offer an easy way to input the date for an album, not for each track, when needed.
Then MB's album year should default to "Album Release Date" when it's set, otherwise to the "latest" track date when different dates are mixed in the same album. Also, all tracks in an album should be sorted by track# in artwork view and album & tracks view regardless of sort criterion. Another benefit of the new field would be sorting multiple albums released in the same year by the same album artist will become much easier because you don't have to re-tag all the tracks to add different month-date value. Also you can tag with original date for each song without much headache about sorting issue.
