Metadata not importing from iTunes to Music Library
I've been using iTunes since its launch probably 20 years ago and I've spent a long time organizing music including adding metadata. Recently prurchased a new MBP and no longer have access to iTunes and need to load all my media into the new Music app. I loaded a few recordings to test the workflow but some metadata appears to be missing. I imported the music files from an external HD working from a complete bootable backup of my previous MBP (High Sierra). On the new MBP (Sonoma), starting in Music, I tried > Import > iTunes > iTunes Media > Music and selected several folders of CD ripped music. The import appeared to go as it should but when I looked in several columns, including "Ratings", "Plays" and "Grouping", there was either no data in "Ratings" and "Plays", or most of the "Groupings" data was missing.
I want to sort out all the potential issues before I attempt to Import all 800+ GB of media. I'm running OSX Sonoma 14.1.2. Thanks for any guidance.
