Lyrics:
Verse 1
White coat lights in a quiet room
Cold blue screens, the numbers bloom
In the bloodstream’s shadow, hidden lore
A silent signal knocking at the door
Pre-Chorus
Not in the flood, not in the plain
Not in the plasma we used to blame
It’s closer than we ever saw
A coded spark behind the draw
Chorus
C4 under the skin, won’t stay still
In the cell’s dark current, it learns your will
Copy by copy, the risk gets loud
A fire in the frontline, inside the crowd
C4 under the skin—now we know where it’s been
Verse 2
Neutrophils carry a private key
Monocytes hold it quietly
Gene-count echo in a protein trace
A tethered charge you can’t erase
Bridge
And if the mind feels stormy, pulled off track
There’s a thread in the body pulling back
Not a verdict, not a cure in hand
But a map you can measure, understand
Final Chorus
C4 under the skin, won’t stay still
In the cell’s dark current, it learns your will
Copy by copy, the signal’s proud
Not in the open—deeper, bound
C4 under the skin—turn the lock, read it in
