Tag editing feature I would like: add string to varying tag field contents

If I select all tracks in a folder the Title field will be: “keep”

I was wondering if there was a way that I could select all tracks and manually edit the Title by appending the same string on all.

An example track list:

Song Number 1

Song Number 2

Song Number 3

etc…

I would like to select all tracks, Title now says “keep” but add a suffix to be added to all Titles that result in:

Song Number 1 (Uniondale NY)

Song Number 2 (Uniondale NY)

Song Number 3 (Uniondale NY)

etc…

This is not something where I want to create an action for it because I will never use “(Uniondale NY)” again.

My suggestion is that, if “keep” (with less-than and greater-than symbols) is a substring of the title then keep the existing Title for that track and add whatever additions were made (prefixes or suffixes).

I did try this just to be sure and of course I got:

keep (Uniondale NY)

keep (Uniondale NY)

keep (Uniondale NY)

etc…

For the new titles. (includes less-than and greater-than characters)

Please try Convert>Tag-Tag for e.g. TITLE
Format string: %title% (Uniondale NY)

Do I need to do something in addition to this… I tried that and I get:

Song Track 1 ( Uniondale NY )

Space after ( and before )

The string constant is that what you enter.
So if you get added spaces, then it is very likely that you entered them.
If not, please show a screenshot of the converter and what you entered.

Sorry, my fault. Once you change the title and if you made a mistake, you have to go back and manually delete the Suffix that you just added. (And then fix the mistake and re-apply Convert–>Tag)

You could use Convert>Tag-Tag again,
Format string: $replace(%title%,My mistake,)
This replaces the string "My mistake" with nothing, i.e. deletes it.

... or use the "undo" function.
