コスモポップファンクラブ (Cosmo Pop Funclub) is a breezy, high-energy space-pop track by Japanese Vocaloid-P and electronic producer ナユタン星人 (NayutalieN). The song features dual vocals by 000 and ナナヲアカリ (Akari Nanawo), with a music video directed by chisaki / ちゃもーい. Its lyrics paint a playful interstellar love story built on astronomy metaphors, dance commands, and the repeated hook "ギブミーコスモポップ" (Give Me Cosmo Pop), all riding a propulsive 189 BPM beat. Originally part of the CHUNITHM NEW!! soundtrack in the ORIGINAL genre, the track was ported to maimai as part of the CHUNITHM area (ちほー) 160 km challenge song set. It arrived in maimai DX UNiVERSE PLUS on July 22, 2022, and notably the International and Asian region releases preceded the Japanese version. The song also appears in ONGEKI bright MEMORY and has been featured in other mobile rhythm games such as Arcaea and GROOVE COASTER Wai Wai Party!!!!. In maimai, the Expert (10+, constant 10.7) and Master (13, constant 13.2) DX charts were both designed by 隅田川星人 (Sumidagawa Seijin). The Master chart in particular leans heavily on Touch-note sequences and holds, totaling 903 notes with 132 Touch notes and 54 Hold notes, a relatively dense pattern for its level that rewards spatial awareness on the DX screen.
