RegEx pattern to limit dashes in these circumstances

Scenario

I use third-party file renaming software that is written in Delphi and supports the pascal script: http://www.den4b.com/?x=products&product=renamer

The application allows you to use regular expressions to rename files. this means that if what I need to do with the file name cannot be performed using only one RegEx, then I could use different expressions at the same time or also pascal-script code to place the file name until I can format it correctly file name for the needs of this question or something else ...

Problem

I need to format the song file names like below in these names: β€œ ... with the artist’s image ” is to the right of the line, I need to match this and put it on the left side of the line.

  • Carbin and Sirmark - Sorry Feat. Sevener
  • Kristjan Cash Cash - Take Me Home Feat. Bebe Rexha (Revoke Remix)

To make this easy to understand, we could imagine the tokenization of the file name as follows:

[0]ARTIST   [1]DASH   [2]TRACK   [3]FEAT_ARTIST   [4]POSSIBLE_ADDITIONAL_INFO_INSIDE:()[]{}

Then, what I need to do with RegEx formats the file name in order to position the tokens in the following order:

[0]ARTIST   [3]FEAT_ARTIST   [1]DASH   [2]TRACK   [4]POSSIBLE_ADDITIONAL_INFO_INSIDE:()[]{}

I really do this with this RegEx:

\ A ([^ -]?) \ S- \ s * \ s ([([]) ((feet [\ s] | feat [\ s] | distinguishing [(.?) ... \ s]) [^ () {} []] *) ([)]])? (. +)? \ Z

Replace with

$ 1 $ 4 - $ 2 $ 7
