Hello!

I am working on automating mine mp3tag and i've just got stuck.

I want to modify my TITLE field.  
It looks like this:

 (feat. , & ) I want replace "&" with a colon but ONLY in the featured artists area. So I thought about sth like this:

```
regexp:
\(feat. (.*)\)

replace:
$caps2((feat. $regexp($1, &,\,)))

```

But it's not working. I need some help with that matter.
