Track info error & divided albums: how to fix track info?
An album of Beethoven chamber music imported to iTunes from my CD somehow got imported as being from two separate albums, so Op 6 track 1 is on one 'album' and Op 6 tracks 2-6 are on another. The album is in storage so I cannot easily access it. The items are all correctly sorted in one folder in Finder and in the iTunes library, with correct track numbers, but if I reimport the whole thing into iTunes again, it keeps identifying them wrong (3 tracks have a slight variation on the title of the album and of the artists).
Can I use finder or similar to edit the erroneous track info somehow so it will all import correctly? Or convince iTunes that when I select all the songs and change the album and artist info to match, it should stick and oh, by the way, that means it is one album? I don't want to use Join together to create linked tracks because I want to be able to play individual movements on shuffle sometimes as well as to play the whole album at other times.
Edit to add: iTunes 12.9.5.5
