Isn't there a field for "composer" for classical CDs?
Nic, yes there is, but I like to search my classical composers on surname: so "Rachmaninov" not "Sergei Rachmaninov" or "Sergey Rachmaninov"; Finzi not "Gerald Finzi". Some systems (eg dBpoweramp) support a ComposerSort tag that organises by surname, but I don't know how universal that is ( and I lost confidence in it when it presented me with "Bingen, Hildegard of"). Anyway, if I make the 'album artist' the composer then I can search by album artist, or by folder, and it all works with my non-classical albums where album artist is "Dylan" or (The) "Clash" or "Elvis Costello and the Attractions" or whatever.
Furthermore where there are two major pieces on a single classical album - say Mendelssohn and Bruch violin concertos, I rip each separately with a different album artist as though they were two separate CDs and avoid all the problems with <Various Composers> etc.
