Thanks very much for MP3Tag.
Whenever a metatag contains a semi-colon, then the export CSV will show wrong columns ouput, as semi-column is the delimiter!
Take for instance
View now this in Excel and you have more than 2 columns
method1: wrap all export fields with "
method2: change ; to another char, I propose _
I would prompt the user (I discovered this by chance) if the export tag fields are not the same as the current viewed tags !!!
Indeed you might view (title, artist,genre, album) and export (title, genre) believing that you actually exported (title, artist,genre, album).
Here it's obvious, but when more tags are involved and having thousand of files, it might be overlooked. Accident happens...
