CANDY TUNE releases a double A-side new single (4th single)! The new title track "Soi So Free" was created around the word "soi," which the members often use in everyday conversation, and the theme of "soi = everyone's correct answer" that emerges on social media and in daily life. In a pop and catchy way, the song expresses both the sense of relief that comes from going along with others, something everyone has probably felt at least once, and the suffocating feeling hidden behind it. "Special Kanshasai" is a new song by Tamaya 2060%, who worked on CANDY TUNE's signature song "Bai Bai FIGHT!" While "Bai Bai FIGHT!" depicted "who they were before the group was formed," this song expresses the changes in their feelings after CANDY TUNE came together and the emotions born from walking forward with their fellow members. This is the CANDY TUNE Edition.
