ピポピポ -People People- feat. ななひら is an electronic track by Japanese producer Neko Hacker featuring vocalist Nanahira, added to maimai DX PRiSM on February 14, 2025. The song's title layers two interpretations: "ピポピポ" (pipo pipo) evokes the electronic beeping sounds familiar from Japanese pop culture, while the English subtitle "People People" creates a phonetic pun, the two phrases sound similar when spoken aloud but carry entirely different meanings. This playful wordplay reflects the genre-blending, lighthearted style that Neko Hacker and Nanahira have cultivated as frequent collaborators in the Japanese doujin electronic music scene. The track was unlocked through the Nanahira Area (ななひらちほー), a dedicated progression area in PRiSM that tied the song's availability to a themed event centered on the vocalist. At 230 BPM, the song drives at a high-energy tempo characteristic of Neko Hacker's production, with Nanahira's bright, signature high-pitched vocals riding over dense synth textures and hard-hitting beats. In maimai, the song receives a full suite of DX charts: the Master chart, designed by ぴちネコ, packs over 1,000 notes including 170 Break notes, while the Expert chart by アマリリス offers a structured introduction to the track's rhythmic complexity.
