"The story behind the bonus OST is really interesting, when we started the development of the re-release of IHNMAIMS we learned from Harlan Ellison that the guy who created the soundtrack is none other than John Ottman who became an award winning composer for Hollywood movies including the most recent XMen movie. We were able to contact his agent and ask him about the soundtrack. Luckily he still had the original Data tapes from his sessions in a storage locker. He paid to have them found and digitized and then finally sent to us so that we could include them with the game. Pretty freaking amazing if you ask me. Not only are they of much higher quality but they also included the 21 additional tracks which never made it into the game. We decided to include them because we thought they would provide some really fascinating content for fans of the game who would appreciate the lengths we went through to offer the re-release and bonus content. They are named "bonus tracks" because they have no other official name!"
