And finally "Classical" music in this context is a red herring, there is nothing different about the methodology of tagging and retrieval of classical Music.  I, for one, like to know who is the composer when I listen to jazz, rock,  and blues, who the players are, what instruments they play etc.

While I agree with you in theory, the Composer-Performer dichotomy in "classical" music genres is of practical significance and not necessarily a red herring. It is an issue that has affected the arrangement of discs in most music stores -- usually by "composer" in the classical section and "artist" in the popular/jazz sections. This is simply the received nature of the classical music canon and industry. Old habits die hard.

I agree that a completely flexible tagging and search methodology is probably the holy grail of what we want. I am an "albums" rather than "tracks" type of listener: if I type "stravinsky boulez grammophon" into the search field, I want to be presented with all the albums I have of Stravinsky's music, conducted by Boulez on the Deustsche Grammophon label. This is my dream but so far it seems unattainable -- unless we incorporate Google-like search algorithms into MPD. Currently I rely heavily on the cover art to identify the correct album I want.
