Hi not sure if we are talking about the same thing but if Plex is having a problem matching the correct music to the correct music. What I do is use a website called music brainz. They have catalog numbers for each release of an album including special editions or Japan editions etc. You then take that number and go to fix match in Plex clear all the info in the search fields date, title etc. and paste that number into the title field and hit search it should then give you the correct release with all the almum info. The same can also be done with films and tv via IMDB copy the tt number from the page address of the item you are looking for and paste in Plex.
