How to organize albums with multiple disks?

Item Structure:

F:\Music - Rock
…Pink Floyd
…Pink Floyd - The Wall
…Disc 1
…tracks
…Disc 2
…tracks

I find MP3Tag the only way to fly (here is ‘Disc 2’ - note: ‘Discnumber’ entry):

I have never actually needed The Plex Dance® for music libraries… but… just in case:

The Plex Dance®:

  1. remove show/movie from library
  2. update library
  3. empty trash
  4. clean bundles
    https://support.plex.tv/hc/en-us/articles/200392106-Library-Actions <— update library, empty trash, clean bundles
  5. bring names and structures into compliance/ or the ultimate bundle reboot operation/ or a generic ‘Re-Do’ Operation
  6. replace corrected show/movie into library
  7. update library

All Steps. In Order. No Shortcuts.
