So, I needed to convert AlbumArtist tag to Composer tag. I used Tag - Tag function and everything came alright. The problem is I types %COMPOSER% which mp3tag recognizes as different and nonexisting tag so it won't let me use Tag - Tag again for used %COMPOSER% tag, I can do it manually for every file when I edit the tag through Alt+T but I got 350 files edited in this way. What can I do to again use bulk?
Where did you type
A screenshot would clarify that.
And now I cannot revert it, even in preview is shows me the %COMPOSER% tag, but everytime I want it to convert to anything else, it shows me blank...
Please add a 3rd screenshot from Alt+T from one of this tracks.
We need to see what kind of tags are still available in your adjusted tracks.
Comparing to manually re-edited
You added the content from %ALBUMARTIST% (correct syntax) to %COMPOSER% (wrong syntax).
You should have choosed COMPOSER without the percent characters (as you would see it in the list pressing the arrow right-button on the right side).
I know I SHOULD HAVE, but the thing happened and I'd like to correct it and I didn't see a solution by myself, so I am asking here.
You can try to choose
%%COMPOSER%% as Format String and copy this content to ALBUMARTIST (without any percentage characters):
Or if you want to have it as COMPOSER choose
COMPOSER as Field.
But why? It will return this
Please try it on 1 of your tracks (ignoring the Preview).
Does it work for you?
It does not.
Please show us again Alt+T from this one test track after pressing OK for the above Format string.
What version of Mp3tag are you using?
(Help -> About Mp3tag).
I ask, because in my Mp3tag v3.19b this works for a test track.
3.19b, I updated it today.
That's strange. I try to reproduce here with your data. Just a moment...
I can't get it work anymore
(I'm 100% sure that I saw a working example before I wrote my answer... )
Whatever I try (Tag -> Tag, Alt + T, Export & Import, the %-Sign with and without quotes, double quotes, backslash) it does not seem to copy the content
into any other tag field.
Maybe @Florian or @ohrenkino knows a trick for this situation?
You can try
$meta(%%COMPOSER%%) as format string.
Yes! This solved my problem. Thank you so much!
