命テステス (Inochi Tesutesu) is a high-energy original song by the artist circle ぱりぱりさらうどん (Paripari Saraudon), performed by the Synthesizer V vocalist Kasane Teto (重音テト). The track was written specifically for the FEAT CONTEST 2024, a competition that invites artists and producers to submit original music for rhythm game inclusion, and took home the maimai DX Award, securing its spot in maimai でらっくす CiRCLE. It later appeared on Paripari Saraudon's debut album 冗談は殴り書きで (Joudan wa Nagurigaki de). At a relentless 240 BPM and clocking in at 1:47, the song wastes no time establishing its chaotic, self-referential character. The title is a layered pun: 命 (inochi, "life") combined with the repeated テステス (tesutesu) evokes both the English word "test" and the sound of a microphone check, a reading reinforced by the very first line of the lyrics, マイクテステス ("mic test test"). The verses spiral through ironic declarations of indifference ("I won't take it seriously, I won't do anything") before landing on the refrain that mistakes, failures, and even stepping on landmines are all part of life's ongoing test. The song balances a frantic, almost anxious energy with a playful shrug, an approach that has resonated well with fans of fast-paced VOCALOID-driven tracks. In maimai, the MASTER chart sits at level 13+ (constant 13.6) and was designed by はっぴー (Happy), while the EXPERT chart (level 11) was handled by Jack. The song also features a unique in-game collection title, 地雷踏んじゃったってそれもテスト ("Even stepping on a landmine is a test"), awarded for clearing the song with exactly 1 MISS, directly referencing a lyric from the track. The music video features illustration by わにうえを (Waniuewo) and movie production by 田中ゆず (Tanaka Yuzu).
