I have a feature request: Is there any way that AS could request the Album Artist from Kodi as a backup if the Artist search doesn't return any results? The reason I ask is that I have some music where they differ and no artwork gets displayed, but would if the search was based on the Album Artist.

It looks like the answer is no. I took a quick look at the Kodi JSON call that gives you back information on the playing song. There is (obviously) an option for Artist, but I don't see one for Album Artist. It's possible I've missed something, but for now it looks like there is no way for Kodi to tell me the Album artist. One thing you could do to fix it manually is to find the MusicBrainz ID for the problem artists. If you paste that ID into the mbid.nfo file that is in userdata/addon_data/script.artistslideshowArtistInformation/[Artist Hash] then AS should download the images. Once something exists in mbid.nfo, AS will never try and update it. That's not an ideal solution if you have lots of problem artists, but it's the best I can suggest for now.

P.S. If you need to figure out what the hashed name of an artist is, you can use Artist Slideshow Helper.

Thanks for taking a look, Kyle!
