Audible.com-Search-by-Album VS Audnexus.bundle

Seanap's plugin for MP3Tag is one that some use to tag their audiobooks for use in Plex.

You don't have to rename the file itself if you don't want to. I just went through a very large audiobook library (over 1,000 audiobooks) to retag the audiobook metadata using the Seanap (https://github.com/seanap/Audible.com-Search-by-Album) MP3tag plugin. I just tagged the file data but didn't change the file name using the Tag-Filename button.

Personally I have a rather large audiobook library in Plex. I've used MP3Tag to properly tag each MP3 file when I've ripped it. Currently use this audiobook scrapper (https://github.com/seanap/Audible.com-Search-by-Album) in MP3Tag which helps with the tagging process. There are likely better ways to deal with audiobooks, for my needs it's working OK for now until something better comes along or Plex adds official audiobook support.

For audiobook tagging, you can always look at this: https://github.com/seanap/Audible.com-Search-by-Album

https://github.com/djdembeck/Audnexus.bundle gets you meta-data updating.

Also I noticed Audiobook.bundle is no longer being actively worked on and has been moved to a different project, Audnexus. If you want to try it, I would use Audnexus because it has a release in March.

If you don't know about Plex, it's a service where you set up your own media server. It's not designed with Audiobooks in mind but I created a Music Library and only put Audiobooks in it. Plex is great and for regular media it will scan all your files and organize it and all the the details, summaries, catalogue and everything as if it were a regular streaming services; but since it's not designed for audiobooks you need to add an audiobook source for it to pull details from. I added Audnexus as my source, it works great.

Third-party metadata agents/scanners still work (e.g. Audnexus is a popular one for getting better audiobook metadata), but there are very few others that do. Ones that relied on their own UI (e.g. anything that integrated with services like Spotify, YouTube, etc) don't work anymore, and haven't for 4+ years. You'll see their entry in the Plugins menu in your server settings, but you can't do anything beyond that because the UI it relied on was removed.

Yes, it's fairly common. In lieu of "official" support, the third-party agent Audnexus can help with organizing things, pulling from online databases that the regular Plex Music agent doesn't (e.g. Audible), and setting tags that can help with navigation (e.g. setting the Style to the narrator, so you can filter to specific narrators).
