Overview
グッバイ宣言 (Goodbye Declaration) is a VOCALOID track by producer Chinozo, performed by the voicebank flower. Released as an independent single in 2020, the song became a phenomenon in the Japanese online music scene, eventually becoming the first VOCALOID song to surpass 100 million views on YouTube, a milestone that cemented its status as one of the defining VOCALOID tracks of the early 2020s. Its upbeat, synth-driven pop production contrasts with lyrics about retreating from a decaying society, a theme that resonated widely during the pandemic era.
In maimai, グッバイ宣言 joined the DX UNiVERSE lineup at launch (September 16, 2021) as part of the niconico & VOCALOID genre. The song's MASTER chart, designed by はっぴー (Happy) at level 12+ (constant 12.8), features 135 Slide notes, a relatively slide-heavy layout for its level, while the EXPERT chart by Jack (level 9+, constant 9.6) focuses on dense Tap and Hold streams. The track also appears in SEGA's other rhythm games CHUNITHM NEW and オンゲキ bright MEMORY, making it a cross-franchise VOCALOID staple.
