I know it is really OCD of me, but if I look in iTunes > Preferences > Advanced at the media path it doesn't put spaces around the slashes.
There are also two possible layouts for the library:
- <Media Folder>/<Artist>/<Album>/[D-]##<Name>.<Ext>
- <Media Folder>/Music/<Artist>/<Album>/[D-]##<Name>.<Ext>
Which one you have depends on a hidden preference file. Again, see Managing your Mac media libraries - Apple Community and the section on iTunes Media Organization for details. The media folder path could include a terminal /Music and the library be in the first layout, or the path doesn't include the final /Music but the library is in the second layout. You may also want to explicitly avoid adding the last /Music folder when rearranging things with the Music app as it seems somewhat redundant.
From your description it isn't clear what the exact value under iTunes > Preferences > Advanced is. Or indeed if you're talking about iTunes when in fact you're running Music under Catalina or later and we should be talking about Music > Preferences > Files when looking for the media folder setting.
Macs have this great feature that, as a rule, you can normally move files from one place to another within the same volume and whatever software has references to those files it will still be able to find them. This means that you can usually manually rearrange content the way that you want to without breaking things. That said, ideally you would let iTunes/Music take care of moving the files and updating its references so that you can be certain nothing gets broken. You mentioned that you thought your paths had too many nested folders. There are two options here. One is to choose a new media folder anywhere, and then consolidate to that folder. This makes copies of everything, which takes time, and if your library is larger than the available free space will fail. After consolidating you have to manually clean up the original files. The alternative is to choose a new media folder at a higher level within the existing path. E.g if the current path is .../Apple Music Library/Music/Media/Music you could pick any of the following to be the new media folder.
.../Apple Music Library/Music/Media
.../Apple Music Library/Music
.../Apple Music Library
Once the new folder has been picked if you turn Keep organized off, and then back on again, the files will be moved to new locations within the current media folder, so no new copies are created, which is a much faster process, and doesn't require further manual housekeeping. Because this is a Mac you could also potentially change the name of the top level folder as a separate action at some point. In either case it is a good move to backup your iTunes or Music library files before making changes.
