I have a lot of files that contain both the artist & title in the Artist field ie:
Tiffany - I Think We're Alone Now
Tried a few things but no luck Any help appreciated
If you need to separate these you could use the Action > Guess Values as %Artist% - %Title%.
If you want to discard the extra data and just keep the Artist, change this to Action > Guess Values as %Artist% - %dummy%.
