Hi Thomas,
I'll send you a file from the 7000, but am not allowed to do so until after it has gone public.

For a database, the easiest without going into the unnecessary complexities of access is to use excel, since the same sets of information can be copied to various pages, and each column - song, style etc then clicked alphabetically for a quick lookup. There are some interesting navigation features on the 7000, I suggest you wait and see what is on offer, then formulate the most useful way to use the features.

I think the most useful program would be one to find duplicate composers.
