 is a song by the Japanese heavy metal band Babymetal. The song was released in Japan as an independent DVD single on October 22, 2011, serving as the first single off the debut album "Babymetal".
Background and release.
The song introduced all three members to heavy metal music; Nakamoto commenting how she had never heard such musical heaviness before, while Mizuno initially had more interest in dancing to the music rather than singing. During song production, the signature Kitsune hand gesture (similar to the sign of the horns) was formed. Vocals for the song were recorded on October 30, 2010. The song's first release was in the Sakura Gakuin album "", released on April 27, 2011, as part of the Jūonbu ("heavy music club") sub-unit.
The song was later announced as a limited-edition DVD single on October 12, 2011, and later released also as a standard digital download available on October 22 and 23, 2011 for pre-sale at the Sakura Gakuin Festival 2011 held at Mt. Rainier Hall "Shibuya Pleasure Pleasure", and later sold in limited quantities on ASmart, Amazon, Tower Records Online, and Tower Records Shinjuku starting October 24. The limited edition included a DVD with the "Doki Doki ☆ Morning" music video and a cut of the original video focusing on the choreography for live performances of the song, and a towel embossed with either the logo of the band or the label Juonbu Records. The single was later released as a CD single on April 6, 2012, packaged with a T-shirt.
The song was later released as a promotional single in the United Kingdom on December 13, 2015.
Composition.
The song has a "modern heaviness" sound in its music, with dark, atmospheric instrumentals that reverse into a catchier and brighter melody with lyrics such as "Rin rin rin! Ohayō, wake up" (Ring ring ring! Good morning, wake up). Kikuchi noted how the tone of the song was directly opposite to Japanese (light music); as a result, the band formed under the label Jūonbu (heavy music club) to signify the contrast. Nakamoto, whose vocals were recorded separately from those of Mizuno and Kikuchi, needed to speak quickly but clearly in the verses.
Reception.
The song managed to peak at number 80 on the "Billboard Japan" Top Independent Albums and Singles chart on the week dated November 7, 2011.
Music video.
Directed by Shimon Tanaka, shooting for the video was completed by October 2011. According to Nakamoto, Tanaka had wanted to appear in the video, but found the choreography difficult to execute. The video was released in an abridged form to the Toy's Factory YouTube channel on October 12, 2011, with the full version posted on the official Babymetal channel over a year later, on November 8, 2012.
"Metal Injection" ranked the music video at number nine on the list of "The Top 15 Metal Viral Videos of the Year" on December 8, 2011.
Live performances.
The song premiered at the Sakura Gakuin concert Sakura Gakuin Festival 2010 at the Yokohama Red Brick Warehouse No. 1 on November 28, 2010. Regarding the group's first performance of the song, Su-metal explained, "What I remember clearly was during the interlude […] we all pretend to fall to the ground...I was afraid that people would just laugh at us and it would be embarrassing, but their reaction made me feel happy and at that time I thought this is who Su-metal is, this is what Babymetal is."
