Hello
I have 1000's of albums that are mainly labelled correctly. Half of Albums are named in this format "Michael Jackson / Thriller" which is how I like it. But some are labelled as "Michael Jackson - Bad" which I do not like. Is it possible to replace Michael Jackson [Space][-][Space] Bad with Michael Jackson [Space][Space][/][Space][Space]. I have been doing it 1 album at a time but will take forever lol. I have attached a photo showing the 2 different ways my albums are tagged and what I am after doing.

Thanks
Load the files into MP3tag.
Filter for albums that still have the - as separator with
%album% HAS -
Check the files whether they should get treated as the - is no good separator but appears frequently in album names as intended punctuation.
Select the files
Create an action (quick?) of the type Replace for ALBUM
Search for: [Space][-][Space]
Replace with: [Space][Space][/][Space][Space]
You know that [Space] represents the character generated by the space bar on the keyboard and has to be entered as a single character and not the string [Space]. Also leave out any [ or ]
@ohrenkino's solution with a Replace-Action should look like this:

Thanks very much. Works a treat. Appreciate your help.
