I just started playing with QtScript in Amarok 2.0.1.1 and so far the documentation has been a big let down. A lot of things are documented for C++ but the conversion into JavaScript is a lot trickier then it looked.

This is ofcourse because the whole QtScript engine is all new and this will become better over time. In this posting I will show what the TrackInfo object holds, which is returned by Amarok.Engine.currentTrack();

destroyed(QObject*): function () { [native] }
destroyed(): function () { [native] }
deleteLater(): function () { [native] }

So the next time you need some information about the currently playing track you know exactly which fields are available.

On a side note: the isValid boolean tells you if the track info you are parsing is in fact a running track. If Amarok is not playing all fields will be empty or zero. Check isValid before you start processing an empty data object...
