PSF rips are often very sloppily done, in my experience. Many of them are incomplete, either because the ripper did a shoddy job, or because he didn't recognize a song and manually removed it before uploading it (yes, some people ARE that stupid). In this case, it could be either of those reasons, or the song could have been removed from localized versions and only present in the original Japanese release (it's probably safe to assume it's not in the International release either if that's the case)
Fortunately, if someone has the knowledge necessary to attempt a rip of the Japanese version, it's a lot cheaper to legally acquire than the NA version; I saw it on eBay for only $20 USD.
