There is a better way to present this media (and avoid any confusion) if the Artist and AlbumArtist are joined together.
The proposal is:- 1. AlbumArtist data is additionally presented as Artist data in cases where they are different (but ignored if they are the same). 2. It is an Optional facility in the Serviio console (users who do not wish to use the facility continue as present). 3. The file metadata would be unchanged. 4. There would likely not be a significant performance overhead as the fields are mostly the same. 5. This would provide a nice option to accessing all artists tracks (whether they are found in Artist or AlbumArtist). 6. The AlbumArtist category on Presentation would become redundant and could be disabled if the user wants to (i.e. only use Artist category).
This would represent an additional feature and benefit of Serviio in providing this facility.
