I seem to remember something from my first days with Plex and when first creating a library, Plex will use the dates from the files/folders on the first scan. Am I remembering this correctly ?
If this is the case and I do decide to create a new library, with my new structure will Plex use the modified date from the top level “Artist”, from each of the separate “Album” folders or the file dates themselves of the actual flac files ?
If you untick “Empty trash automatically after every scan” and Plex recognises that it already knows the track, it shouldn’t appear in Recently Added. This way you also can just move files from A to B, not having to take them out, scan, and put back.
This is how I rename my TV episodes, and move the folder structure around.
