Shooting Shower～DANCE TIME(シンディ)～ is a crossover track from Sammy Corporation's pachislot machine DISC UP, brought into maimai でらっくす FESTiVAL PLUS as part of the April 1, 2023 update. The song plays as the background music during the ART bonus game called DANCE TIME when the character Cindy appears on the reels, a detail reflected in the song's parenthetical subtitle (シンディ). The jacket art originates from the DISC UP ORIGINAL SOUND TRACK album, and the track is copyrighted by Sammy. In maimai, the song sits in the ゲーム＆バラエティ (Game & Variety) category at 149 BPM and features four DX charts. The MASTER chart (level 13.0, constant 13.0) was designed by DANCE TIME(サファ太), a name that itself winks at the song's subtitle, and is built around synth-aligned patterns for most of its duration. Its most memorable moment comes at the very end: a large "S" shape formed entirely of Touch notes flies across the screen, a direct visual nod to the "S" in Sammy. The EXPERT chart was designed by はっぴー (Happii).
