Misia remarked to Excite that she usually tries to take a few days off from singing before a concert, but had to make do with less vocal rest because of her busy recording schedule. She expressed being surprised that the final vocal take for "Aitakute Ima" turned out so well, despite the less than ideal conditions.^[7]
