“Your example above contains a mistake many people make:
Album Name - Chilled Euphoria (CD 1)
If this is a multi-disc album, the disc number must NOT be part of the ‘AlbumTitle’. There is a proper metatag just for disc numbers. Make use of it.”
Same as above comment. I am declaring both the CDNumber and NumberOfCDs in EAC and checking this in MP3Tag and so I can’t see how the AlbumTitle can cause a problem. I understand that Plex will not use “(CD x)” in AlbumTitle to differentiate and uses the values in CDNumber for this function.
The AlbumTitle will cause a problem, if that is what you are embedding in the Albumtitle meta tag.
Let’s say you have a double album.
You embed Chilled Euphoria (CD 1) into all tracks of disc 1.
and Chilled Euphoria (CD 2) into all tracks of disc 2.
Result: Plex will make 2 albums, one named “Chilled Euphoria (CD 1)” and the other “Chilled Euphoria (CD 2)”, instead of one album named “Chilled Euphoria” with 2 discs in it.
Using
Chilled Euphoria (CD 1)
and
Chilled Euphoria (CD 2)
as folder names on disk however, is tolerated by Plex (as long as the embedded metadata are in order).
“After you changed the embedded tags, perform a [Plex Dance]”
1.move all files for the show out of ‘sight’ of plex - By this, do you mean to change the directory path Plex uses to find media (in my case Z: drive which is mapped to my NAS Music folder) or do you mean to remove all media from Z: to another location not searched by Plex?
I mean moving the files themselves (or better, the whole folder of this particular album).
Do not touch the library configuration.
“I recommend to use a subfolder approach for multi-disc releases. to store on disk

This is a good suggestion and is something I have considered indeed. Are there any issues that arise from this method?
“side car” AlbumArt needs to reside in the subfolder for disc 1. That’s it.
True ‘single’ tracks (which don’t appear on any named release) don’t get an AlbumTitle tag.
Those will be collected by Plex into a ‘virtual’ album called ‘[Unknown Album]’"**
I have always added the AlbumTitle tag to all of my media. By “Single” do you mean, for example, a CD single which would have 3 or so tracks by the same artist or just a track on it’s own? I would still populate the AlbumTitle tag as either the track name or single name on these, unless there is problems caused by this.
I am doing the same when I have the complete ‘single’ release from the artist with all its different ‘mixes’ and B-sides etc.
I treat and tag them just like albums (often I include (CDS), or (EP) or (maxi) in their “album” title).
But sometimes you happen to have just one single mp3 file of a song. And sometimes there are even several of these ‘lone’ tracks for a given artist.
For most of these I am simply too lazy to determine the album or single where they appeared on. This is what I was referring to.
