Sprintrances is an instrumental original track by Taishi (河合泰志) that first appeared in maimai PLUS, the December 2012 update to the first maimai arcade release. The song was not originally made for maimai, it was composed for HALFPIPE TOKYO, a digital-reality attraction at SEGA's Tokyo Joypolis theme park. Its genre within that attraction is listed as "Trance Step," a fusion of drum-and-bass and trance that defines the track's driving beat and layered synth melody. The title itself is a portmanteau of "Sprint," "Trance," and "Step," reflecting the song's intended synergy with the high-speed, wind-in-your-face experience of the Joypolis ride. Taishi, active in the doujin and game music scenes under labels such as Arte Refact and as part of the unit Edelritter (alongside Nhato) and Electro.muster, brings a polished club-sound sensibility to the maimai catalog. The Master chart, designed by mai-Star, sits at difficulty 13 (constant 13.3), while the Expert chart was designed by ニャイン (Nyain). The song's jacket was updated starting with maimai でらっくす Splash to include the title text; the original jacket featured only the mechanical animal CG artwork. The music video, produced by HD LV (Kodai Endo), shows a metallic creature racing through a neon cyber-space, visually echoing the attraction's theming.
