本OST中其实并无“Her Spaceship”一曲，steam商店中的曲目表上，取而代之的是- mystery track-一行。而同时在OST文件夹中有一个“hello from the hat in time team.txt”，有以下内容:
hello!!!!! thank you for buying our soundtrack!
if you own A Hat in Time, check out the HatinTimeGame folder it has neat stuff that might fill a hole in your heart thx
A Hat in Time Wiki中亦有提及：
While Grant Kirkhope, known for his music in the Banjo Kazooie games, did compose the hub theme "Her Spaceship", he asked for it to be left off the album for unknown reasons.
