The newer Plex Music agent is a lot more powerful than the ‘Plex Music Scanner’ agent, but it is also much pickier about the accuracy of your tags, as well as the folder structure of your media files. For instance, if your folder structure looks like below, and the artist or album tags in the files don’t match the folder names, Plex may not get it right. You’d think it would be less dependent on the folder structure if the tags are right, but that’s the way it is.
/Music
/artist - album
01 - track name
02 - track name
or
/Music
/artist
/album
01 - track name
02 - track name
The ‘Plex Music’ agent is also less tolerant of missing or incorrect/inconsistent metadata tags. Believe me, I was involved in some of the testing of the new agent, and I was surprised to find how many problems I had in my tags!
This guide may be of some help.
Once I had all those issues ironed out, the new scanner turned out to be much better than the old one. In addition, the “Plex Dance” is almost never required with the new agent.
One additional note: This pretty much applies to non-classical music. Plex has some work to do to be truly useful for correctly-tagged classical music.
