On March 21, Cube Entertainment's new 7-member male idol group, BTOB, has released their debut digital single. The group's debut tracks titled "Insane" and "Imagine" has been released on various online music websites.

The two songs will tell the same story through a different genre and will feature a distinctly unique charm from each other.

The first title track, "Insane", has been produced by Seo Jae Woo, who has composed songs for other Cube artists such as 4minute and B2ST. While the second title track "Imagine" is an R&B ballad and will differ from Insane. It will prominently showcase BTOB’s appealing vocals as well as a refined melody.
