Ok, I have uploaded a bunch of MP3 files that you can grab here:
http://ul.to/l16dgeu7
It includes the following:
1. Camouflage/Various Mixes
Various songs from Camouflage taken from different albums
tagged with Picard and then tag fields amended with Tag&Rename
Album Artist = Camouflage, Album = Various Mixes, Compilation = off
2. Depeche Mode\Stranglove (Maxi CD)
Maxi-CD with additional songs
tagged with Picard; verified with Tag&Rename (no changes necessary)
Album Artist = Depeche Mode, Album = Stranglove (Maxi CD), Compilation = off
3. Depche Mode/It's No Good (Maxi CD)
Maxi-CD with additional songs
tagged with Picard; verified with Tag&Rename (no changes necessary)
Album Artist = Depeche Mode, Album = It's No Good (Maxi CD), Compilation = off
4.Madonna/Like a Prayer
ATTENTION: THAT IS JUST A TEST! Actually it is the Album "Delta Machine" from Depeche Mode
tagged with Picard as "Depeche Mode - Delta Machine", but revised with Tag&Rename afterwards
Album Artist = Madonna, Album = Like a Prayer, Compilation = off
5. Various Artists/Various Hits 2007
Four totally songs from diffrent artist and different albums (Monrose "Hot Summer", Monrose "Shame", Rihanna "Umbrellal" and "Take Tat "Patience")
tagged with Picard and then tag fields amended with Tag&Rename
Album Artist = Various Artists, Album = Various Hits 2007, Compilation = ON
I used XBMC 13 Gotham Nightly Built 20140126-b6d31a3-master and Universal Artist Scraper / Universal Album Scraper for scraping. In Settings / Music the option "Download additional information" was enabled, and the option "Allow online data to override music tags" was disabled.
Expected result: Artist should be listet as named in "Album Artist"-tag. Albums should be incldued under respective Artist with names provided in "Album" tag. Metadata (Biographies, Album-Infos) should be grabbed as provided in the Musicbrainz-IDs
Actual result: Chaos. Artist and Album-tags seem to be ignored. Somehow the Musicbrainz-IDs seem to be preferred for sorting and naming.
Please do not blame me for the albums and songs I picked. That was just a spontanious selection for testing purpose :-)
Btw: This is just for testing (as requested). Please delete these songs afterwards because of copyright reasons - of course.
Brgds,

PS. I used the latest Alpha-Version of Picard for tagging. In settings you are offered to enter certain tag-fields that should not be overwritten when tagging the files. In this latest release those fields can be separated by commas (not spaces anymore, like in previous releases), which makes it possible to also exclude "Album Artist", "Album", etc from being overwritten. However, when I used Picard those field were overwritten anyway. So I had to "correct" them afterwards using Tag&Rename. But it seems that XBMC is ignoring those "corrections" and just using the infos scraped from the MB-IDs for sorting and naming.
