OptimistImanishi

A sad piano rock number that sings of giving up on oneself.
It’s producer Imanishi’s debut and breakout hit, released in 2021.
A highly addictive waltz that makes you want to call it a “bundle of pure style.” Both the melody and the lyrics give the impression that the protagonist’s thoughts are spilling out in an unending stream.
“I know it’s not right, but this is all I can do.” Haven’t many of us felt that way at some point?

Carlos Hakamada, a Vocaloid producer also known as “Saize-P.” “Otonari-san Chi no Universe” is a denpa-style track he created featuring the virtual singer Hoshikai.
While the song centers on rapid-fire verses, it deliberately shifts the rhythm and pitch here and there to create a more chaotic vibe—that’s the key.
Under the band name Dynamic Jienzu, Carlos Hakamada has produced many high-energy songs as well.
