# Heart Electric

"Heart Electric" (ハート・エレキ, Hāto Ereki, also "Heart Ereki") is the 33rd single by the Japanese idol girl group AKB48. It was released in Japan on October 30, 2013. The participating members for the title track were given English nicknames. The single reached number one on Oricon and Billboard's weekly charts.

## Promotion and release

During AKB48's annual rock-paper-scissors tournament held at the Nippon Budokan area on September 18, 2013, AKB48 announced the lineup for "Heart Electric", and the release date of October 30. Haruna Kojima was announced last and come out with a red skirt in contrast to the blue skirts of the other members; this indicated that she was the center of the single. This marks Kojima's first time as a solo center. The group then performed the song and introduced themselves with English nicknames.
The single was released in nine editions: four regular, four limited, and a theater edition. The limited editions contain a ticket for a handshake event and a randomly selected sticker of one of the 16 nicknamed girls. The regular editions are the same as the limited editions except that they contain one of 48 photos instead of the handshake ticket. The Type-K edition has a DVD documentary about the graduation of Sayaka Akimoto.

## Musical style, writing, composition

The song was done by RoopSounds, who had previously done "Skirt, Hirari". The music is described as being like a marching band. During the performance, Kojima does a roll-call of some of the participants, each of whom has an English nickname. This was explained as being according to band protocols.

## Music video

The music video for Heart Electric was directed by Shusuke Kaneko who is known for the Heisei Gamera trilogy, Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack, and the live-action film adaptation of Death Note. The video premiered at the group's handshake event at the Osaka Dome. It is described as girls competing for individuality in a band called "The G. Fingers". Kojima, who plays Michelle, said that "there were a lot of scenes we shot for the music video, and remembering all the nicknames for the band members was really difficult."
