The only Artist info in tags is Artist Name.
The Artist Information folder can be anywhere but typically is root folder and not under any music source folder. If you don’t specifically set an Artist Information folder then Kodi presumes you are using its original Artist\Album folder hierarchy with only one music Source folder (i.e the Artist information is in the Artist folder and all Artist albums are there also).
I found some good info about the Artist Information folder here:
https://kodi.wiki/view/Artist_information_folder
Of particular interest to me is this information in the "Recommended Setup" section:
A frequent question from users is
what do you recommend?, in the case of the Artist Information Folder the answer is simple: unless you have local artwork for artists, or want to enter artist information via NFO files there is nothing to do. For a first time Kodi user the recommendation is to tag your music files accurately, scan them into the library and allow the scrapers to fetch additional artist and album information and artwork for you.
With v18 you can arrange your music files however you like and still have access to local art and NFO files. We would recommend that all the music files from an album are kept in a unique folder, perhaps with subfolders for each part of a multi-part set. Perhaps you choose to arrange those in artist folders of some kind, but that does not have to be strictly adhered too. You could divide a large music collection by genre (with an artist having albums in more than one), or by decade, or some broader music category e.g. Xmas music. Use an
Artist > Album > Songs structure if it is convenient for you.
Once you start to extend your use of Kodi then a number of situations can arise:
- you have artists that the scraper was unable to find information or art for
- you want to manually edit some of the information
- having selected particular art from the many choices the scraper has found, you want to backup that choice
- you want to transfer your current library to another installation of Kodi
I don't currently have local artwork for artists, unless the "cover" file in most of my album folders counts as that. The only NFO files I have are for concert and music videos I have split and tagged with MMH, but when MMH asks if I want it to scrape, I've always answered "No," so I, assume the NFO files just have minimum data.
I don't know if I'll ever import local artwork for artists, but I might go back and create new NFO files for my concert videos using the Scrape function in MMH. Would that also work for my music video collections as well?
Even if I don't do any of that, I can see the advantage of the "artist - album" format over the "artist/album" format in terms of moving albums to different source folders. Does the "artist - album" format absolutely require the Artist Information folder? That's not clear to me from the wiki I quoted because it says, "Use an
Artist > Album > Songs structure if it is convenient for you."
