hop, drum and bass, and dubstep. The opening track "Babymetal Death" is an instrumental speed metal track, with frequent shouts of "Death!", while "Gimme Chocolate!!" features "thrashing, grating guitars" that alternate with "speed-sung, quirky lyrics". Songs like "Megitsune" and "Iine!" are notable for their sudden genre shifts, while the Su-metal solo "Rondo of Nightmare" is described as a powerful cacophony. The Black Babymetal song "Song 4" incorporates elements of reggae, while "Catch Me If You Can" contains elements of "digi-rock" (digital rock) and industrial metal. "Ijime, Dame, Zettai" begins with a mellow intro transitioning to speed metal. Lyrically, the songs of the album are in Japanese, and focus on issues for young girls, like acceptance and standing up for one's self. "Megitsune" is about women who hide their emotions like a kitsune (fox), which serves as the band's signature hand gesture. "Gimme Chocolate!" talks about girls who like to eat chocolate, while dealing with the worry of weight gain, while "Iine!" emphazises the band's desire "to establish a fun, aggressive, new genre in music". "Doki Doki ☆ Morning" and "Uki Uki ★ Midnight" are described as two sides of a day, and as such describe the contrasting times of a girl's life. "Catch Me If You Can" has a more comical theme of hide and seek with concepts of Japanese namahage. "Headbangeeeeerrrrr!!!!!" tells the story of a girl's first experience at a concert, while "Ijime, Dame, Zettai" is an anti-bullying theme. According to Nakamoto, the meanings behind lyrics of the songs did not immediately become recognized by the members of the band, but this would later be mitigated after performing the tracks live in concert. After the album gained international attention, Nakamoto has mentioned how a girl from the United Kingdom sent a letter about how "Ijime, Dame, Zettai" helped her deal with school bullies, and further said, "Despite the fact that we sing in Japanese, so many people around the world have reached out to us and that encourages us to keep doing what we are doing right now. We are definitely happy that we've been able to help our fans in any way we can."
