I have albums tagged as Albumartist:"Various Artists" but amarok ignore that. He shows Various Artists As Various Artists in collection only, when i choose "show as various artist" from amarok (but program "knows" that it's various artist, because if i choose album made by various artist that was tagged before adding to amarok, i can choose "dont show as various artist" (even though it's not showing it in this way anyway)).

Known issue - please search this forum for other topics about "various artists". Also search http://bugs.kde.org
