Plex Mix - Playback Error

I’m running my Plex Media Server on iMac and I’ve added over 20,000 tracks to the library. I wanted to try out a Plex Mix with my tracks.

When I try it out, I get the following:

Playback Error - An error occurred loading items to play.

I have optimized my database, I have repaired a corrupt database.

Attached is my log of the server. Can someone help me out to get Plex Mix to working again on Plex?

Thank you in advance.

I’m having the same error. Server version 1.13.0.5003 on a Mac running OS X 10.12.6

@dklein -

Try the following and see if this works for you:

  1. Get Organized.

When you add media to Plex, you should always have the formation of your folders as

Plex Media/Music/

If you have a lot of A letter artists, create a naming scheme that will allow Plex to add your content with ease and zero confusion. If you had folders such as:

Plex Media/Music/A

This naming scheme could haywire if you have an album later in your additions that is titled ‘A’

Try:

Plex Media/Music/Artist (A)

This is secure and won’t confuse Plex.

The last thing with getting organized is make sure you add the most amount of music in a given artist first and go to least.

In other words, let’s say you have 200 A artists, 60 D artists, and 10 M artists. Don’t add D, A, and M. Add A, D, and M. This is will help you stay consistent with Plex as it attempts to acquire data.

  1. Optimize!

Make sure after every single addition you make to your library you optimize. Without Optimizing Database, the database
could get stuck on you and the database won’t run smoothly. Plex has this feature to ensure that everything goes well.

  1. Enjoy!

Create Plex Mixes, create mood based playlists. Explore everything Plex Music has to offer especially as a Plex Pass subscriber.

Last thing, make sure that if you run a cleaner software to keep your computer up to date to never delete data for
Gracenote.

The files .gdb are responsible for making Plex Music work especially with Plex Mixes. These files are inside the cache folder within your install on your computer.

I hope this helps those adding a large library.

Thanks!
