@10%,
again, thank you for sharing your experience.
Yesterday, I"ve made a little research on how BS5 displays (=uses the tags of) cd-samplers:
BS5 has a very strange sorting order... within its groups "album" and "cover" it sorts by the wma-tag "contributing artist", and not by "album artist" which results in a huge mess of double/multiple album entries.
Unlike WMP, BS5 does not support common 1:n relationships (1 Album : n Artists) when grouping by albums or covers.
The workaround - as you described - costs its price: once you replace the "contributing artists" tag with the "album artist" tag, you are one logical step away from finding one track of a special artist which was sold on a cd-sampler.
I'm very unhappy with this...
One should know if the cleanup of the a.m. "logical potential" is on B&O's todo-list. A possible workaround which should help to keep the "contributing artist" information might be the following workflow (using a tag-editor:
1. copy "contributing artist" to any other unused tag field (maybe: "composer")
2. copy "album artist" to "contributing artist"
3. copy the tracks/albums to BS5
once B&O matches the a.m. logical relationships between artists and albums, the contributing artist might be copied from its parking position back to its native tag field in one simple batch process.
