Just a few further comments ...
I've tried installing this set of files on a completely fresh PC just to see what the information as you guys would be seeing it. I was slightly surprised at the colours and fonts in the explorer views. I have used <right-click> OPTIONS to set the scheme I wanted and I didn't appreciate that wasn't saved anywhere in the data I posted. For example some of the links in AlbumBrowse, especially for Various Artists albums, are almost indistinguishable from standard text. Please feel free to adjust locally to suit your preference.
Similarly, depending on your Windows fonts you may find that some of the forms have words chopped off or odd spacings. Just adjust the choice of font or size to fit.
(Ooops, yes, I should know better. Strictly speaking a 'font' includes the definition of size. The actual characters - glyphs, anyone? - are the 'typeface'. The combination of a typeface plus size, etc is what constitutes a 'font'.)
Also, if I were starting from scratch I'd now make the track-level fields for catalogue, and opus etc look-ups. It is essential in my way of working to have consistent catalogue numbers, otherwise links to find all instances of a given work by catalogue number won't work. So BWV 1014 (with one space) is not the same as BWV 1014 (with two spaces). A look-up won't actually prevent inconsistent data, but it reduces the likelihood of error and makes subsequent checking and correction much easier.
Finally I just spotted that the two versions of Nielsen's 3rd Symphony in my database had been given completely different catalaogue numbers!
How could I? Of course, as you all knew, the Fog Schousboe catalogue number for the "Sinfonia espansiva" should be FS 60, not FS 29 as I had in one version. Any idiot knows FS 29 is the second symphony!
