Search and Replace Artist and Artist in Title.....?

I have a bunch of tracks where my artist name is the same as within the title itself. I need to remove it from the title part without corrupting the title part. How do I use the %artist% field to subtract the exact match from the %title% field?

Here is one of my examples:

Artist:GRANDMASTER FLASH & MELLE MEL

Title: GRANDMASTER FLASH & MELLE MEL - WHITE LINES

Not sure how to make it search and replace the match....

Thoughts?

If Your files are all in the format you say they are then this will do the trick.

Action type: Guess values
Source format: %title%
Guessing pattern: %artist% - %title%

I am a friend of filters as I have my doubts that a pattern I think I found is really prevailing.
So:
I would apply a filter to reduce the number of files really to the ones that match your criterion.
"$strstr(%title%,%artist%)" IS 1
And then, as the artist is already in the title and they are both the same, it is easy to simply overwrite the artist.
So a custom made action of the type "guess value" for
Title
and the value
%artist% - %title%
should do it.

Works perfect, thank you. I was trying to do it with the replace command, keep forgetting about guess values

Thanks!
