"Music Flyer" is a song recorded and performed by Japanese collective unit E-girls, taken as a promotional single of their third studio album E.G. Time (2015).
It was written, composed, arranged and produced by Japanese musician and Capsule member Yasutaka Nakata, marking the band's first collaboration with him, and was co-produced by Exile Hiro.
In order to promote the single, it was used as the official theme song for the Japanese social app 755, which also starred selected members from E-girls, and was performed on every date for their 2016 Colorful World tour.

[9] In a similar analysis, Patrick St. Michel from The Japan Times believed the track was inspired by the effects of the Korean wave, namely the musical element of K-pop.
[11] It is one of two original songs from E.G. Time to feature all remaining vocalists of the band up until E-girls and Flower member, Chiharu Muto, left both groups in October 2014; these singers are Shizuka, Aya, Ami, Erie, Karen Fujii, Ruri Kawamoto, Reina Washio, Kyoka Ichiki and Yuzuna Takebe.
He believed "Music Flyer" was the only example from E.G. Time where E-girls "buck most of the major idol trends", and additionally "shun idol-standard amateurism in favor of K-pop-like precision,".
[17] Members Shizuka, Aya, Ami from Dream, Karen Fujii and Kaede from Happiness, and Shuuka Fujii and Reina Washio from Flower participated in two live commercials; the first showcased each member performing "Music Flyer" on stage with additional information about the app, while the second featured Aya chanting to the girls as they all go towards the stage; Ami is then seen using the app on her phone.
[18] On December 16, both AKB48 and E-girls members Washio, Karen and Shuuka Fujii and Kaede made an appearance at a press conference talking about the app and "Music Flyer".
