I have hundreds of tags that show the name of a classical composition in the Album field, like this: "Suite for Orchestra No. 1 in D Minor, Op. 43, TH 31". They have arrived in that form because I've created a title field by converting the file name, and then used a "format value" action to copy th…

You can use an action: Action Type: Guess values Source format: %composer% Guessing pattern: %composersort%, %dummy% This type of action uses an unique separator. In this case it is the comma with a space behind. The content before the separator goes to COMPOSERSORT, the erst into nirvana. …

Instead of "Replace" the action-type command would be "Format Value". To add the composer's last name would be easy if you have a tag-field filled with this information, for instance the field COMPOSER or COMPOSERSORT. Action Type: Format Value Field: ALBUM Format String: %composer%: %album% Yo…

Thanks for your thought. Unfortunately, I have no field that contains only the composers' last name. However, in the both the composer and artist fields, I have that info, along with the first name. It's presented two ways: Aaron Copland (artist); Copland, Aaron (composer). I found the way to add …

[image] MP3TaggingJ: I found the way to add a new field, and can call it COMPOSERSORT. There is no need to add this field manually. The action "Guess values" creates this field.

I must be missing something, but I don't know what. Here's what I did, which I think is the long version of what you've suggested. I create the new column and name it COMPOSERSORT. I place my cursor in that column, in a row that has "Copland, Aaron" in the Composer field. I select Action - Guess Va…

[image] MP3TaggingJ: However, no text appears in the COMPOSERSORT field. If I understand your approach correctly, at least the text of my format string should appear there, which would obviously be incorrect. You need to proceed as follows: Load all files into Mp3tag you want to treat thi…

I'm sorry, but I followed your directions previously, and then went through your checklist again this time. I selected a different set of files as well. However, the script produces no new text.

Do you look at the content of your created column? Maybe the definition of the column is wrong. You should show us a screenshot of your column definition. It has to look like this: [image] Mark a file and have a look at the extended tag-view (ALT-t). Do you see a field COMPOSERSORT there with you…

You found where I made my mistake. I'd never created a new field before, and when I did this one I didn't fill in all the necessary info at the top of the template. The "value" field was left empty. When I filled with %composersort%, your "guess values" action worked, even for "compound" names like …
