Well I hope it is called "various artists" in Amarok, in german it is "Verschiedene Interpreten.

I have one album in the various artits section, but i don't like this behaviour. So I selected "Do now show under various artists" (Well, "Nicht unter verschiedene Interpreten anzeigen") from the context menu of the album, but nothing happened, it is still there (as a part of various artists). But now "Show under Varios artists" is shown in the context menu.
