Thanks for the considered reply, Zhenya. When I do a GetInfo of Craigie Hill in iTunes, it lists Paddy Tunney as the Artist, the "Album Artist" whatever that means, is blank, and the album is listed as VOP 04, etc., just as it was entered into iTunes by GraceNotes. It is also checked off as part of a compilation.

Well, I just took that whole CD and copied the "Artist" names to the "Album Artist" column. All that did was to re-order the whole CD in iTunes alphabetically, but the artists still don't show up in my iTunes Artists menu. (Yes I did sync the iPod). Still no Paddy Tunney.
