さんさーら！ (romanized as Samsara!) is a GAME & VARIETY track from maimai DX UNiVERSE, credited to ARuFa, an internet personality and creator known for a playful, anonymous online presence. Behind the scenes, the track brings together two notable Japanese music figures: composer Hidekazu Tanaka of MONACA (the prolific production house behind countless game and anime soundtracks) and lyricist Pinocchio-P, one of the most well-known Vocaloid producers in the doujin scene. The song's title is a pun on the Buddhist term samsara (輪廻, the cycle of rebirth), written in hiragana with a prolonged vowel and an exclamation mark to give it a bright, almost childlike energy that contrasts with the weight of its source concept. Musically, the track sits at a steady 140 BPM with a pop-rock arrangement typical of Pinocchio-P's melodic, slightly quirky style. ARuFa's processed vocal delivery, reminiscent of Vocaloid tuning, fits naturally alongside the composer's MONACA-polished production. In maimai, さんさーら！ features four DX-standard charts. The Expert chart was designed by はっぴー (Happy), while the Master chart, rated 12+ with a constant of 12.6, was designed by サファ太 (Safata). The song was initially added to the Chinese version of maimai DX UNiVERSE on September 22, 2021, and later appeared in CHUNITHM NEW PLUS. Notably, さんさーら！ was removed from the maimai song list starting with 舞萌DX 2024 (China) on September 4, 2024, and from Asian versions in maimai DX BUDDiES PLUS shortly after, making it a limited-time offering that players can no longer access in current cabinets.
