In some songs I have redundant artist information that I would like to correct.
For example
`> Victoria Monét, Earth, Wind & Fire, Hazel Monét; Earth, Wind & Fire & Hazel Monét`
`Earth, Wind & Fire, Hazel Monét; Earth, Wind & Fire`
What I like to get is
`> Victoria Monét; Earth, Wind & Fire; Hazel Monét`
`Earth, Wind & Fire, Hazel Monét`
How can I correct this and similar with an rule based action (i.e. REPLACE)?
Best would be an action that identifies and corrects redundant artist information in general.

For this pattern, there is a very simple solution, but may not suit all your examples. I learnt about Guess values the other day!
Action Guess values
Source format %title%
Guessing pattern %title%; %dummy%
This gives you everything before the ; and discards (via %dummy%) from the ;

This is basically true but does not check in any way if the part after the `;` is the same as the part in front of the `;`
The OP only wants to remove redundant (identical) information that occurs twice.

What about this answer:
> [@COPYRIGHT - eliminate redundancy](https://community.mp3tag.de/t/copyright-eliminate-redundancy/61494):
>
> In the COPYRIGHT field I often find strings like 2023 Blues Route / Delta 2023 Blues Route / Delta The texts contain a different even number of words. I would like to eliminate the obvious redundancy in the text. After correction, I would like to get the following: \> 2023 Blues Route / Delta How to do this?
and this answer
> [@Minimize redundant information](https://community.mp3tag.de/t/minimize-redundant-information/63648):
>
> There is redundant information in many of my albums. I can correct a lot of this with rule-based macros. I like to have INVOLVEDPEOPLE as preferred information. PERFORMER often contains redundant information. How should a check or reformatting for the attached example be formulated? Can it also include PRODUCER?

I found a way to solve this! 😃
I divide the tag into multiple tag occurrences and use the function REMOVE DOUBLE ENTRIES.
