Blew Moon is a hardcore techno track by t+pazolite, marking the artist's first-ever contribution to the maimai rhythm game series. Released on July 11, 2013, as part of maimai GreeN, the song showcases t+pazolite's signature happy hardcore style, a driving four-on-the-floor beat, rapid sampling vocals at the intro, and bright, uplifting synthesizer melodies that accelerate the mood throughout. Despite being composed during a cold season, the artist himself describes the track as having a refreshing, almost summery character, playfully linking the song to watermelons and swimsuits in his commentary. The title "Blew Moon" is a deliberate respelling of "Blue Moon." t+pazolite (real name Tomoyuki Hamada), a member of the HARDCORE TANO*C label and founder of the doujin circle C.H.S. (Cutie & Headshaking Sounds), has since become one of maimai's most prolific and recognizable composers, with Blew Moon serving as the starting point of a long-running partnership with the series that would produce many more original tracks. Over the years, Blew Moon's charts have undergone more level revisions than most maimai songs, adjusted across nearly every major version as the game's difficulty rating system evolved and the charts were re-evaluated. The song received a Re:Master chart on July 28, 2016, as part of maimai PiNK PLUS, designed by はっぴー (Happy). Its jacket was also updated starting with maimai でらっくす Splash, adding the song title text that was absent from the original design. An extended version, "Blew Moon (Uncut Edition)," appears on t+pazolite's album REALLY Don't waste me!.
