All songs

Overview

The phrase "はいよろこんで" (Hai Yorokonde) means "Yes, gladly", a cheerful, deferential expression that singer-songwriter こっちのけんと (Kocchi no Kento) repurposes into something far more layered in his 2024 viral hit. Co-arranged with producer GRP and accompanied by a music video directed by かねひさ和哉, the song pairs an upbeat pop production with lyrics about overwork, emotional suppression, and the exhaustion of performing happiness for others. Its most memorable hook, "ギリギリダンスギリリギリダンス" (Giri Giri Dance, or "edge-of-the-line dance"), spread rapidly across TikTok and YouTube Shorts, while the chorus embeds the Morse code signal for SOS (・・・ーーー・・・) as a subtle distress call beneath the dance-floor energy. はいよろこんで arrived in maimai でらっくす PRiSM PLUS on March 13, 2025, appearing in the POPS & ANIME category across Japanese, international, and North American regions. It launched the same day in CHUNITHM X-VERSE, marking the artist's simultaneous debut across both Sega arcade rhythm platforms. The maimai chart set spans five DX difficulties, with the Re:Master chart (designed by Jack at level 13) presenting the densest layout at 838 total notes. Lyrically, the song weaves in scattered English phrases, "Save this game, Mr. A", and the Swahili phrase "ハクナマタタ" (Hakuna Matata), contrasting carefree imagery against its sardonic commentary on people-pleasing and burnout.

Trivia

The song was co-arranged by producer GRP alongside Kocchi no Kento, who handled composition, lyrics, and vocals himself.
The music video was directed by かねひさ和哉 (Kanehisa Kazuya).
The Morse code pattern '・・・ーーー・・・' (three short, three long, three short pulses) embedded in the lyrics is the international distress signal SOS, a thematic counterpoint to the song's outwardly obliging 'yes, gladly' refrain.
The same SOS pattern appears as the title of the track skip achievement in maimai's でらっくすコレクション.
The one-MISS achievement title 'はい謹んで' (Hai Tsutsushinde, 'Yes, humbly') and the FULL SYNC title 'あなた方のため' (Anatagata no Tame, 'For you all') are both direct quotes lifted from the song's chorus.
A green title called '緑のマルチアーチスト' (Green Multi-Artist) requires playing 死ぬな！, どんぐりGAME, and はいよろこんで in a single credit.
The song made its rhythm game debut simultaneously in both maimai DX PRiSM PLUS and CHUNITHM X-VERSE on March 13, 2025.
The lyrics briefly reference 'ハクナマタタ' (Hakuna Matata), the Swahili phrase popularized by The Lion King, used here as a descriptor for the carefree-sounding melody.
The English line 'Save this game, Mr. A' appears in the second verse, one of the few English phrases in the otherwise Japanese lyrics.
The single was originally released in 2024 and gained widespread traction on short-form video platforms before being licensed for Sega's arcade rhythm game lineup.
