Overview
ベースラインやってる？笑 (Baseline Yatteru? Warai / "Are You Doing the Baseline? lol") is a buoyant electronic pop track by prolific composer かめりあ (Camellia) featuring vocalist ななひら (Nanahira), added to maimai でらっくす Splash PLUS on May 14, 2021. The song originates from the duo's split album ふぉーす！ (Force!), continuing a creative partnership that spans multiple rhythm game franchises including SOUND VOLTEX and beatmania IIDX. The title's casual, self-aware tone, capped with 笑 (warai), the Japanese internet equivalent of "lol", mirrors the playful energy of the production, built around a driving bassline and Nanahira's characteristically bright vocal delivery.
The song's appearance in maimai DX arrived alongside a WACCA crossover: the jacket art uses the same illustration featured in that game, with the album title swapped for the track name. The Expert chart, designed by 隅田川星人 (Sumidagawa Seijin), stands out for its dense Touch-note layout, 108 Touch notes out of 524 total, or roughly 20% of the chart, making it a practical choice for players seeking to sharpen their DX touch-sensor accuracy. The Master chart, crafted by はっぴー (Happy) at a 13.4 difficulty constant, packs 692 notes with 53 Break notes, presenting a demanding all-around test of speed and precision. The Basic difficulty was later revised downward from level 4 to level 2 starting with the UNiVERSE+ update, reflecting a post-launch recalibration of the entry-level experience.

Trivia
- The song is from the split album ふぉーす！ (Force!) by Camellia and Nanahira, marking one of several collaborations between the two artists across the rhythm game scene.
- This is Nanahira's second vocal appearance in maimai, following 進捗どうですか？ (Shinchoku Dou Desu ka? / "How's the Progress?") which was added in an earlier version.
- Camellia and Nanahira are both frequent contributors to Konami's rhythm game series, their music appears regularly in SOUND VOLTEX and beatmania IIDX, and they have released split albums together outside of game commissions.
- The jacket illustration is shared with WACCA, another rhythm game that features this song; the only difference is the title text replaces the original album title.
- The Basic difficulty was originally rated level 4 when the song launched in Splash PLUS, but was lowered to level 2 beginning with the UNiVERSE+ version update.
- The Expert chart contains 108 Touch notes out of 524 total, an unusually high proportion (~20.6%) that makes it one of the more touch-intensive charts at its difficulty tier.
- Playing with two or more human players and clearing with exactly 1 MISS unlocks the humorous title: 「はい…本当に申し訳ないと思っています…反省文も書きます…」 ("Yes… I'm really sorry about that… I'll write a letter of apology too…"), which matches the song's self-deprecating online-culture vibe.
- The suffix 笑 (warai, literally "laugh") in the title is standard Japanese internet slang, analogous to typing "lol" at the end of a sentence in English.
