Question about the licence model and browsing through music

[Music-Guy]

I also think that there has been some confusion here.
Therefore, I will try to present it again in a simplified way

the structure currently looks (simplified) as follows:

• Artists
• ...
• Audio Type Filter
  • Compilations
  • Audio Books
  • Music
  • Podcasts
    

Within the sub-items of "Audio Type Filter", under the item "Compilations", there is an intelligent browsing list with ALL audio files that are tagged accordingly.

Under the item "Music" there is also an intelligent browsing list, which (with the exception of Audio Books and Podcasts) contains ALL other audio files.

Here, the separation works exactly as desired.

However, the situation is different under "Artists".
There, all artists are listed that are also displayed within "Audio Type Filter" -> "Music" -> "Artist".
In addition, however, also SOME of the artists of audio files that contain the tags COMPILATION=1 and ALBUMARTIST=Various Artists.
But only some and not all. And I can't see any pattern why these some elements are listed there, but others are not.
