The Fnaf 2 Menu theme actually came from a stock track by Bjørn Lynne called "The Sand Temple". It was actually bought by Scott Cawthon as a loop, a small piece of the song, to use in-game. I took the full original version and made it start where the iconic title screen loop started, but didn't cut it so it shows the full extended version of the theme, without the intro. If you want to hear the full thing that includes the beginning, It is on youtube, and the fnaf 2 part starts at exactly 1 minute and 40 seconds in.
