The readings on jasrac just replace the symbols with Star/Flower, but I'm not really sure naming a track Star Star Star Star [...] Flower Flower Flower Flower is a good idea. I think it's better to stick to the booklet.
There are also three more "tracks" that aren't on the soundtrack, all by
Keiichi Hirokawa. I suppose these are just the sound effects that play from the character's phones.
