I'm not sure if this is a bug or an error on my part.

```
$regexp(%artist%,(\sF\w{0,8}[\.gt]\s|\sand\s|\swith\s),' & ',1)

```

(The actual code is longer but this just the relevant part.)

I use this in the Tag-Filename, to replace variations of 'Featuring', 'And', 'With' in %artist% names with an ampersand.

Notepad++ and all the online regex testers I've tried find the correct matching, except mp3tag 2.77

So All variations of 'Feat.' etc should be ' & '  
Here's some output example;

Maze Feat. Frankie Beverly --\> **Maze Feat. & Beverly.mp3**  
Maze with Frankie Beverly And More --\> Maze & Frankie Beverly & More.mp3  
Gene Testing Featuring The Somegthing --\> Gene Testing & The Somegthing.mp3  
Gene Testing Featg ag Somegthing --\> Gene Testing & ag Somegthing.mp3  
Gene Testing Feat. The ding Somegthing --\> Gene Testing Feat. The ding Somegthing.mp3  
Gene Testing Ft. The Somegthing More --\> Gene Testing Ft. The Somegthing More.mp3  
Gene Testing Feat The Somegthing --\> Gene Testing & The Somegthing.mp3  
Gene Testing And ding Somegthing --\> Gene Testing & ding Somegthing.mp3

_In the first line intrestingly 'Frankie' has been replaced._

Excellent program btw.

Try:

$regexp(%artist%,'(\sF\w{0,8}[.gt]\s|\sand\s|\swith\s)',' & ',1)

Thanks ohrenkino.  
Adding the single quotes actually works. Would have never thought of it.

Still on a learning curve, only discovered this fantastic program a few weeks back.

Thanks to all.
