クレイジークレイジーダンサーズ (Crazy Crazy Dancers) is a high-energy Touhou Project arrangement by COOL&CREATE members beatMARIO and Amane, built on the stage 5 boss theme "Crazy Back Dancers" from 東方天空璋 ～ Hidden Star in Four Seasons. The arrangement was shaped by a three-way collaboration between ARM (IOSYS), Komso (狐夢想), and beatMARIO himself, three veteran doujin music producers whose styles converge into a dense, cheeky dance track that takes its "crazy dancer" motif seriously both musically and lyrically. The lyrics, co-written by Komso and beatMARIO, are packed with Touhou in-jokes: a sung "O T Z Y" chant (a phonetic nod to ZUN), a reference to Eirin Yagokoro ("えーりんえりん"), and the punchline "太田" (Ōta), a well-known bit of fandom wordplay. The Re:MASTER chart, designed by 小鳥遊さん, famously mirrors these vocal gags through its slide-note patterns, tracing sequential O → T → Z → Y shapes and culminating in a slide formation that draws the kanji 太. Originally added to maimai FiNALE on February 22, 2019, the song debuted with an animated background featuring Satono Nishida and Mai Teireida, the two boss characters from the source game. This was replaced by a static jacket in maimai でらっくす. The track also crossed into SOUND VOLTEX VIVID WAVE (pre-released at Reitaisai 15 in May 2018) and Groove Coaster 4EX, extending its reach beyond the maimai arcade.
