[4] However, while this was happening, the band were contacted to write a theme song for the Tsuyoshi Kusanagi drama 37-sai de Isha ni Natta Boku: Kenshui Junjō Monogatari,[1] which disrupted their plans for the single.

[8][9] Originally the band intended for "Music" to be the leading promotional track for Sakanaction and not released as a physical single before it was chosen as a drama theme song.

[14] This was related to discussions the band had three years prior, where they wanted to use their name in katakana for their general musical releases and "sakanaction" for instrumental songs.

[26] The band created extended versions of "Inori" and "Structure" with a stronger club music sound, in order for the release to appeal to DJs.

[25][26] The remixes were created in collaboration with Aoki Takamasa,[26] who had worked with the band on the album versions of both "Inori" and "Structure", arranging and mixing the compositions.

[29] The video shows Sakanaction wearing sunglasses on a stage and standing behind Apple notebook computers, as fans in the crowd dance to the music.

Kazuki Namba of Rolling Stone Japan was impressed with "Inori", describing it as a song that progresses by the power of only its choir-like vocal chorus and beat.

[32] He was impressed by the song's new approach, to the degree that he was disappointed when the rest of Sakanaction did not show similar signs of growth.
