Strange eh?
Not really
This is a scanning issue, not a scraping or NFO one, and I might ask the forum mods to make a separate thread for us.
Unfortunately Jarvis, you don't say so I'm guessing that you are using 16, still can not handle some of the default ways that Picard tags music files. I am hoping to fix this in Krypton, make it totally Picard compatible and flexible, meanwhile you will need to do some tag tweeking if you want to avoid the outcome you currently have.
First let me explain what has happened, just in case it helps someone else. You have the following tags:
Album Artist = Jeremy Healy & Allister Whitehead
Musicbrainz Album Artist Id = 1d2bcb45-2c15-4482-bde2-bffac1221573/8d2477a6-03bd-4fc8-a4b5-ac22dc566841
But no ALBUMARTISTS (note the s) tag. Picard is going to implement this (AFAIK), but may not have done so yet. Kodi reads 2 mbids, easy to parse because they have a standard format, but only one artist name. Some times "&" is part of a single artist name, sometimes it is joining two names, Kodi can not tell which. Mismatching count of album artist and mbids can result in the mbid being used as the artist name, or other confusion because Kodi in some cases tries to use the artist name instead.
The solution (for Jarvis) is to add ALBUMARTISTS tags to the songs of these albums that identify the individual album artists when there is more than one. This can be separate tags if using ID3 v2.4 or FLAC/Vorbis or a single tag using the Kodi default item separator e.g. ALBUMARTISTS = Jeremy Healy / Allister Whitehead if v2.3
An alternative solution is to change the ALBUMARTIST tag to use the Kodi item separator e.g."Jeremy Healy / Allister Whitehead", but this will be what you see listed and the "&" may be important to you.
I am reasonably sure that where you are seeing mbids as artist names it will always be down to a mis-match in the number of names to mbids, and no ARTISTS or ALBUMARTISTS tags. Remember that Jarvis can only split names using the item separator (space slash space by default).
Sorry that you feel Kodi has made a mess of the library. In the longer term correctly identifying individual arrtists and using mbids will make for better music browsing and selection (and accurate scraping of additional arrtist data. artwork etc.), but unfortunately the tagging process still needs some manual intervention. I could do with someone updating the wiki to explain this but don't have the time myself.
