Can you provide a complete example of input paths and desired output file names?

They don't have to be real file paths, but they have to capture all relevant aspects, e.g. different folders, different names, different extensions, etc.

We'll see what can be done once you provide a complete example.

This custom ordering by extension can be achieved by inserting an appropriate number in front of the filename, according to its extension.

This can be applied with a Pascal Script rule:

var
  Order: Integer;
  Extension: WideString;

begin
  Extension := WideUpperCase(WideExtractFileExt(FileName));

  if Extension = '.DFF'       then Order := 1
  else if Extension = '.DSF'  then Order := 2
  else if Extension = '.WAV'  then Order := 3
  else if Extension = '.AIFF' then Order := 4
  else if Extension = '.MP3'  then Order := 5
  else if Extension = '.M4A'  then Order := 6
  else                             Order := 7;

  FileName := IntToStr(Order) + '_' + FileName;
end.

So your example list will look like this:

1_Song 1.DFF
1_Song 2.DFF
2_Song 3.DSF
3_Song 4.wav
3_Song 5.wav
4_Song 6.Aiff
5_Song 7.mp3
5_Song 8.mp3
6_Song 9.m4a

You can now sort this list of files by the Name column, then remove the order prefix, and then apply a Serialize rule.
