I'm in a band and for decades we have kept a backup of all our demos on the Music app on a desktop Mac, way back to the days of it being the iTunes app... before streaming was invented. Each time we have replaced the Mac, we have transferred the music files (currently a 2021 M1 iMac running Tahoe).
However, the Music app has started to act a little strangely. Previously the file structure for the music files was this: Macintosh HD > Users>(User name)>Music>Music>(Band name)>(Album name)>(File)
Since moving to Tahoe, however, it's this: Macintosh HD > Users>(User name)>Music>Music>Media>Music>(Band name)>(Album name)>(File)
So now there are two different file locations for songs dragged to Music, despite them having the same artist name.
Also, if you change the album name of a song by using Get Info on a song name in the Music app, it renames it in the Album view (and on transfer to iPhone) like it always has. However, now it doesn't change the name of the album folder in the Finder.
How can I get the Music app to sort itself out so the file structure is consistent again? I don't want to have to reinstall every song from scratch... as well as the band files there is a lot of other music, nearly 12,000 songs in total.
