1. LUFS is disabled
2. ID3 tags should be fine. This issue was present before I started manually tagging with MP3tag.
3. I might be wrong on the playback reporting not working, as I needed to wait for the entire track to finish for it to show in the plugin page. Testing with the official Jellyfin Desktop Client (Windows).

I went back and did some additional testing. I am unable to reproduce the issue on a completely fresh Windows Jellyfin install (10.3). I wiped all the directories before installing.

Though it took multiple attempts, the issue is still present on my main server (Linux Debian service) after adding the playback reporting plugin. I briefly added all the plugins and matched the settings and I can’t get the clean Windows server to break. I’ll have to dig deeper on the main server to see what may be causing this.

For me the issue wasn’t present at the start of 10.9, but it was very annoying for someone that would add around 15 new tracks a week.

At the bottom of this forum thread I posted some screenshots. This was a while ago, before I started dissecting my setup. Essentially, after adding a new track or album, there was about a 66% chance that it wouldn’t have the artist as you can see in the screenshots. After I started tagging my music and setting the covers to “Front cover” instead of putting them as separate jpg files, it wouldn’t pick up the cover for anything.

I spun up a fresh install of the latest version and when I removed that plugin, everything started getting the proper metadata. It was a reproducible issue.

This also happened with my home video library, where it wouldn’t get screen grabs for the thumbnails. Movies and TV series were fine though.

I’m not 100% sure on the next bit, but it also seemed like the playback reporting plugin wasn’t working at all even on the fresh server. After playing media and waiting, it would never get populated. So combine that with my previous issue, and the fact that it hasn’t had an update in a while, I thought it was just incompatible with the current version and cut my losses. I just wanted to get my server working back the way it was and it was an issue I’ve been dealing with for months, so I removed the plugin.

I haven’t done any recent testing though, and couldn’t find much discussion on if others are having this issue.

Of course this has nothing to do with what you’ve made. It’s not your fault the plugin isn’t working in my setup, and it isn’t the plugin’s fault Jellyfin is lacking the proper data for you to work with natively. Hopefully I can re-visit this issue and get it working in the future.

This looks cool! Unfortunately it requires the playback reporting plugin which I removed as it causes issues with later versions of Jellyfin (for me at least). Even with a clean server I found the plugin wasn’t pulling any data and made it so album art and artist information wouldn’t show up without a manual scan of each track. I was still able to find some interesting stats without the plugin though. Thanks!

It’s closed source, but Symfonium has had smart playlists for a while, if it’s a feature you’re willing to switch for. It’s great to see this feature in the Jellyfin server, and hopefully all the apps can implement it in due time.
