ポップミュージックは僕のもの (Popmusic Wa Bokunomono) is a pop-rock track by the Japanese band ONIGAWARA, added to maimai as part of the MURASAKi edition on March 9, 2017. The song originally appeared on a self-produced album of the same name released in December 2014, available only in select regions before being re-recorded for the band's first nationwide album エビバディOK? (Everybody OK?) in 2015. ONIGAWARA, members Satifour Takeuchi and Shin'ya Saitou, who handled composition, arrangement, lyrics, and vocals, wrote the song as a deliberate theme song for themselves, a confident declaration of their musical identity. The accompanying music video was produced by the creative group REGALO. In maimai, the track spans Standard charts from Basic (Lv4) through Master (Lv12, constant 12.5), with the Expert chart designed by チャン@DP皆伝 and the Master chart by 譜面-100号. A distinctive later addition was the UTAGE (宴) cooperative chart, added in maimai DX BUDDiES on September 14, 2023. Titled ポップミュージックは僕たちのもの, shifting the possessive from "mine" (僕) to "ours" (僕たち), the chart supports two simultaneous players. The song was removed from all maimai arcade versions on March 13, 2025, making it no longer accessible on current cabinets.
