About the music track #14 "tyrant"

I just downloaded the 40 meg zip file linked from the Tribute Site that contained Cave Story music. And I noticed that the track #14 "tyrant" was missing. I looked through the Doukutsu Monogatari Uploader site and found an mp3 of remix of the track and I don't think I heard that track in the game.

Is it not in the game or did I miss something through my play-through? If it's not in the game, how'd people know that song's included in the tracks?

 

It plays when you see the Doctor in the Sand Zone and on the Balcony. Use OrgView to hear the original version if you don't remember it.
