Some more answers and other responses: Paul, I believe that iTunes does not "re-download" new Gracenote data unless you explicitly request "Get CD Track Names" from the "Advanced" menu. If this is too awkward for you, you can completely obliterate your cached Gracenote data as per my previous e-mail. To do this, delete the file found at "Home > Library > Preferences > CD Info.cidb" (i.e., drag it to the Trash and Empty Trash). This technique "works for me" (iTunes 6.0.1). Note: Rob mentioned "iTunes Music Library.xml" but I believe that file is only used if you have "imported" your CDs into your "iTunes Library". It does not pertain to the information displayed for a physical CD. Likewise, downloading fresh data from Gracenote would not modify any previously-imported "iTunes Library" items (if any).
As for the quality of the data, I am also the type of person who would get disappointed if other people didn't take care with their inputs to Gracenote. I am also the sort of person who notices spelling and punctuation errors, omissions, etc. However, I"ve not personally noticed errors or slackness with classical CDs in Gracenote. The only problem that springs to my mind is variability in whether people cite the performers or composers in the "Artisti" field. Also, there can be stylistic differences in the way that people annotate individual movements as tracks. Also, it's a shame to hear that you've tried contributing corrections back to Gracenote unsuccessfully, and I can understand your frustration with that aspect. James.
