A fan account on Twitter  stated that Airi answered a question during one of her events about why Good Night was missing from the album trailer, and she and her manager said that it was missing because of an issue with the composer, among other possible reasons. That could be why Good Night is missing from iTunes as well. I assume it's kind of like Juice=Juice's issue with Vivid Midnight, where it was missing from the the single on iTunes, and the songs had to be bought separately instead.
