Creator Profile · DECO*27: The 'Commercial' Flag-Bearer Who Welded Pop Melodies into VOCALOID
VOCALOIDCreator ProfileDECO*27If some producers turned VOCALOID into art, DECO*27 turned it into pop music itself.
In the early VOCALOID scene, where a 'woe is me' vibe was everywhere, DECO*27 was one of the first to prove that 'anime-style vocals could produce radio-ready pop songs.' From his first upload in 2008 to now, he almost single-handedly turned 'catchy' into a compliment for this craft.

The 'Pop Machine' That Releases One Song a Month
After his debut, DECO27 maintained a pace of *roughly one upload every one to two months**, with songs like "Ai Kotoba," "Shinkai Summit," "Nisoku Hokou," and "Tsumi to Batsu" each surpassing a million plays and entering the 'legendary' ranks. This frequency is almost industrial in a scene that runs on inspiration, and he achieved it through solid compositional skills: he started learning guitar at 13 under his father's influence, began teaching himself composition in the second year of middle school, and after being blown away by livetune's "Packaged" in college, he switched to DTM—outside of formal training, it was all deliberate practice.
Style Coordinates: Sharpness Beneath a Sweet Surface
DECO27's songs have a fixed recipe: *a catchy major-key melody + dense lyrical content + a touch of unease*. "Ghost Rule" (2014) is the pinnacle of this aesthetic—the chorus is sweet as candy, but the lyrics are about "lies, time limits, taking and being taken." A saying circulates in Chinese fan circles: listen to a DECO27 song with a smile, and you'll feel terrible by the end.
