Seems to work correctly in all of my tests thus far.

Sidenotes (for consideration for future versions):

• Using or including a space character in the Merger could improve output readability in some use cases (when the resulting filename is split into multiple lines in a file browser), however currently using a space character as Merger results in: "Error: Missing a 'Merger' parameter" and when used as an additional character, like this: --Merger="; " it gets ignored unless another character is added after it.
  
• Not sure if placing the standard Merger between the original filename and the first addition is always ideal, but i don't see any significant drawbacks to it either. Replacing it with an optional prefix (and possibly suffix) option(s), would solve any potential issues though.
  
• When a file includes multiple audio tracks, there is no separation of any kind between their readouts.
