Perhaps not so much a wish but more a suggestion to see what others think.
Currently sorting fields are named such as:
sort artist
sort album artist
sort composer
To me it would seem more natural to have them named:
artist (sort)
album artist (sort)
composer (sort)
Also in any listings they then would also sort (phun intended) nicely directly below 'artist', 'composer' etc, and not a lot futher away under the 's'.
