YOU SAID:

There is a secret symphony at the center of the world, and its song is like razors through flesh; I'm here to turn up the volume.

INTO JAPANESE

世界の中心にある秘密のシンフォニーと肉をかみそりのようなその歌は私は音量を上げるにはここです。

BACK INTO ENGLISH

The secret Symphony is in the center of the world and the flesh is the song like the razor I turn up here is.
