Hello there, usually this works well.

The track it's not doing anything to though is "20 Broken (Featuring Amy Lee).mp3"

I can't understand why it's not changing the formatting to "20 Broken (feat. Amy Lee).mp3?

Please let us copy & paste your existing regular expression and don't let us type it character by character.
Your screenshot is fine, but please add the regex formatted as code like this:
(?i)(\s)f(?:ea)?t(?:(?:\.?|\s)|uring)(?=\s)

BTW:
If you use a code snippet from this forum please read the exact use case.
This one is for some derivates of "featuring" if it is has a leading space.

Your example has an opening bracket (not a space) in front of "Featuring".

And your replacement text has also a space in front of ␣feat.
This would make "20 Broken ( feat. Amy Lee).mp3" if it would match at all.

Try this:

find

(\s?)\bf(ea)?t(uring)?\b\s?\.?[^\w]

replace

\1feat.space
change the word "space" to real space

For those who prefer a preview in Tag -> Tag:
Formatstring:
$regexp(%TITLE%,(\s?)\bf(ea)?t(uring)?\b\s?\.?[^\w],feat. ,1)

Hint:
The replacement feat. will replace both variants (uppercase and lowercase) F with a lowercase f as the OP asked.

Needs to be like this:

$regexp(%TITLE%,(\s?)\bf(ea)?t(uring)?\b\s?\.?[^\w],\1feat. ,1)

There should be \1 for cases like this:
Something featuring (featuring noone)

You are right.

Whyever someone wants to see "feat. " twice:
Something feat. (feat. noone)
as result.

As always:
Be careful with such edge cases. The space between feat. and the opening bracket ( in
Something feat.␣(Featuring noone)
will be duplicated and results in
Something feat.␣␣(feat. noone)

The same is true for
Something featuring (Feat.␣noone)
which results in duplicated spaces after the second feat.
Something feat. (feat.␣␣noone)

␣ = space, just for better readability.

You've got a point.
Take a look at this, might work better:

$regexp(%TITLE%,(\b\s)?\s*\bf(ea)?t(uring)?\b\.?(?:(\s*|[^\w])),\1feat. ,1)

With my testings it turns this:

Mrs. X FT.         FT FEAT     FEAT. FEATURING    Ft ft Feat feat Feat. feat. Featuring featuring Mr. Y
20 Broken (Featuring      Amy Lee)
20 Broken (Feat      Amy Lee)
20 Broken (       Feat.      Amy Lee)
Something featuring     (featuring noone)
Something feat.      (featuring      noone)
Something           feat.      (featuring      noone)
Something featuring     (feat.      noone)
Something feat.     (feat.      noone)
Something feat     (feat      noone)
Something feat.     (      feat.      noone)
Something feat     (        feat      noone)
Something featuring (featuring noone)
Something feat. (feat. noone)
Something feat (feat noone)

Into this:

Mrs. X feat. feat. feat. feat. feat. feat. feat. feat. feat. feat. feat. feat. feat. Mr. Y
20 Broken (feat. Amy Lee)
20 Broken (feat. Amy Lee)
20 Broken (feat. Amy Lee)
