Comment 46 for bug 355308

David: that is not current policy. When Jaunty was released, it shipped Amarok 2.0.2, which unfortunately is already very old. To include a newer version, Amarok 2.1 should have been released before the feature freeze for Jaunty. As this was not the case, it goes to the backports.

FYI, there is absolutely nothing we can do about that, it is the feature policy for Kubuntu, and happens to a lot of other applications too who do not release at the same time as Kubuntu does. And that's what the backports are for: backporting newer versions of applications.

If you don't want to get the newer package from the backports, you will have to wait for Karmic Koala aka Kubuntu 9.10 to be released.
