Money Money is a Touhou Project vocal arrangement by the doujin circle 暁Records (Akatsuki Records), featured in maimai FiNALE since its December 2018 launch. The track is an arrangement of "今宵は飄逸なエゴイスト (Live ver) ～ Egoistic Flowers," the battle theme of the Yorigami sisters, Joon (the wealthy, narcissistic older sister) and Shion (the perpetually impoverished younger sister), from the fighting game 東方憑依華 ～ Antinomy of Common Flowers. The thematic contrast between wealth and poverty carries directly into the song's lyrics, which the arrangement by Stack (暁Records' longtime vocalist and lyricist) turns into a glossy, nocturnal club anthem about insatiable material desire. Stack handles arrangement, lyrics, and vocals, delivering a performance that swings between seductive and desperate as the narrator pleads for money, rings, and watches, then pivots to ask whether happiness can really be bought. The official music video, produced by カフウ and 原之, matches the neon-lit dancefloor atmosphere with animated visuals. In maimai, Money Money's MASTER chart (level 13, constant 13.2) was designed by 小鳥遊さん (Takanashi-san), while the EXPERT chart (level 10+) was designed by LabiLabi. The chart has seen notable level rebalancing across maimai versions: originally debuting at level 12 in FiNALE, it was raised to 12+ in Splash, then to 13 in UNiVERSE+, while the Advanced difficulty was bumped from 6 to 7 starting with FESTiVAL. The frequent adjustments reflect the chart's continued relevance through the transition from the original maimai series to the DX line. Money Money was released on the eponymous 2018 album "Money Money" by 暁Records.
