. . . I can't seem to get the string to convert anymore? 
Mozart uses "(KV)" references. But if I change "(BWV)" to "(KV)" nothing is adjusted? Should I be doing something different, please?
The difference is the space I believe. There isn’t one in the Mozart naming after KV, but there was in the Bach BMW names.
Thanks Motley,
I actually thought I'd tried that, but I'll give it another whirl tomorrow . . .

If you really use
Search string: \s*\(KV\s*\d+-\d+\)
for TITLE then it is not amazing that it does not work - as that pattern describes a number range: KV \d+ (digit) - \d+ (digit)
But as far as I can see the TITLE has only "KV digit"
You would need the pattern for TITLE again:
Search string: \s*\(BWV\s*\d+\)
Present or absent spaces are taken care of with \s* which means "zero to many spaces"
Hi ohrenkino,
I was able to remove the "(BMV)" text from 3 Bach CD's (TITLE and ALBUM fields), thank-you.
But I can't seem to delete such data from Bach's 'Brandenberg Concertos', I'm afraid.
Bach: Brandenburg Concertos (BWV 1046a-1051,1060-1064)
It would be amazing if I can get this one amended, please.
Cheers,
Paul
I think that this time it is possible to get rid of anything following "(BWV"
So please try this
Search string: \s*\(BWV.*
Replace with:
(leave empty)
As the pattern is the same for ALBUM and TITLE, use it for both actions, the one for ALBUM and the one for TITLE.
Did you know that a double-click on the column divider in the file list fits the colum width to the longest string in that column?
So, if you want to show us the contents of ALBUM and TITLE, double-click their dividers and then create the screenshot. Screenshots that do not show the whole data of a field leave out the most important pieces of information for a possible solution of the problem.
I was not aware of this function, thanks.
This dividers work similar to the column dividers in the spreadsheet software "Microsoft Excel".
In addition, you can click on a Mp3tag column header and sort the content (the complete row, not only the cells in the selected column) either in ascending or descending mode. This can be very helpful to see empty cells or different cells grouped together.
Hi LyricLover,
I think I have round it now, thanks!

This is the foldername. Rename that after you have set all the tag data right.
The (probably) corresponding album data can be set with the new expression that deletes everything following "(BWV".
The album with "(Fischer)" can be treated with the already known expression for ranges.

I have two versions of Bach's "Preludes & Fugues"; one by Keith Jarrett and the other Edwin Fischer. By having each performer's name in brackets enables me to identify between the two versions.
The pattern is the same as long as you have the extra name in brackets
