With such code
$filename(C:\Users\USER\Documents\! Mp3tag export list.txt,utf-16)$loop(%TITLE%,1)%TITLE% $loopend()
I can create a list of all the titles that I have. And if two or more files have the same value in TITLE, then it is not repeated on the exported list
How about adding something like
#### REPEATS: X
at the end of such TITLE that was repeating itself [and the X being a number of them? Can it be done in Mp3tag or would it have to utilize some functions of for example Notepad++ [which would have to operate on a list including every instance of a repeating itself TITLE]?
