Okay, things seem to be working now. Here’s everything I did:
- Reinstalled and restarted Plex to get back the Local Media Assets and put them first
- Made sure every file had a tag value for Artist, Title, Album, and Album Artist. The first three were all fine but I went ahead and filled in Album Artist for everything. In the case of a compilation, the Album Artist is the name of the compilation, otherwise it’s the same as the Artist
- redid all track tags as simply ## (01, 02, etc.) instead of “01/12” and so on. I’ve also been removing the disc number unless there are for real multiple discs.
- redid file structure. Plex used to like it the way I had it but now I am doing
Music/Subsection/Album Artist/Album/Track - Title - also redid the file structure to move all my music subdirectories under a “Music” directory. I only use Plex for music, but I had a Movies directory and some other stuff at the main level, now all music is in one subdirectory.
- When creating a library, I am using Plex Music, checking Prefer Local Metadata, and unchecking everything else
Three folders have now imported correctly, and I’m working on a fourth. Many, many thanks to everyone who helped me get here. @Ismelda, @beckfield, @BigWheel, thank you for your patience!
