I notice when I edit certain fields in the extended tags window, they show up as all caps in windows.
for example before editing in mp3 tag in windows I see;
Artist: Cyndi Lauper
Album: The Body Acoustic
Year: 2003
I then notice I have the wrong year, so I load this into mp3 tag to change year to 2005 & I add a new field; & Type it Catalog Number
After these edits in windows it shows up;
Artist: Cyndi Lauper
Album: The Body Acoustic
YEAR: 2005
CATALOG NUMBER: CD2
why does mp3 tag capitalize these? when I run a quick action case conversion to mixed letters for the field name
I get;
Artist: Cyndi Lauper
Album: The Body Acoustic
Year: 2004
Catalog Number: cd2
It seems to not only convert the field name, but also the info after it, in this case CD2 to cd2. I would like it to just change the cases of the field names.
how do I get mp3 tag to not capitalize the field names when I edit info for them?
