Someone once helped me with this before the forum changed and I have been searching through the forums again. I was hoping someone could help me out again. I, still, after these many years struggle to understand the scripting ideas. I want to add a disc subtitle to the album tag in Picard not in the file naming but the actual tagging of the file so iTunes will recognize. Example ‘The Beatles in Mono: Revolver’ for the album tag of the Beatles in Mono disc of Revolver. Any help is appreciated, thank you Musicbrainz and Picard. I love the app and site.
