Yummma releases “ランクアップ (Rank Up)” on November 4 as a digital single, according to ABEMA Times. It’s her first track since the EP BAD BLOOD, released in July. Production by RhymeTube.
RhymeTube is not an underground rap name. He produced FARMHOUSE’s “distance,” Rin音’s “snow jam,” 空音 (Sorane)’s “Hug feat. kojikoji” and SUSHIBOYS’ “DRUG,” tracks that reached well beyond hip-hop listeners. He also runs his own label, which held its first event in Tokyo in October with FARMHOUSE and Kee Rooz. For yummma, this is a shift in register after BAD BLOOD.
“ランクアップ” follows yummma’s childhood, shaped by her mother’s successive partners. Each new man changes the home, the meals, the activities. Two images sum it up, per ABEMA: “泥水から水道水” (doromizu kara suidōsui, “from muddy water to tap water”) and “カップ麺から一蘭” (kappu men kara Ichiran, “from cup noodles to Ichiran,” a ramen chain). Life ranks up, but the child chose none of it. The lyrics separate material comfort from family happiness.
RJHH covered “お金がない” (Okane ga nai) in October, a track about being broke that drove her first wave on TikTok and Instagram Reels. BAD BLOOD already dealt with neglect and family violence. “ランクアップ” keeps that autobiographical material, but RhymeTube sets it to a more electronic sound.
