Hannes,

I haven't heard of this ITApplication before, but for your specific
problem, I think it's clear why [currentTrack
isKindOfClass:[iTunesFileTrack class]] evaluates to true: in the
previous line, you defined it as such, like this:

iTunesTrack *currentTrack = [iTunes currentTrack];

So obviously it is an iTunesTrack!

Try this:

iTunesFileTrack *currentTrack = [iTunesFileTrack currentTrack];
NSLog(@"%@", [currentTrack location]);

Since iTunesFileTrack is a subclass of iTunesTrack, it should work,
giving you the info you need.
