Lyrics:
Verse 1
Midnight in the lab, bright screens in a row
Tiny broken letters in a bloodstream flow
We used to read one side, thought that was the map
Now the other ending whispers where the shadows snap
Pre-Chorus
Flip the strand, feel the pattern change
Every cut leaves a signature, never quite the same
Measure the silence at the edge of a chain
And the noise starts making sense again
Chorus
Four ends, one signal, clear in the sound
Motifs in the margins turning lights around
From fragments to answers, we’re getting so close
A sharper heartbeat in the data we chose
Four ends, one signal—follow it home
Verse 2
Size by size, the story shifts its weight
Different hands of enzymes set the timing of fate
DNASE1L3 draws clean lines in the dark
While others leave their rhythm like a spark on spark
Bridge
Not just the five-prime, not just what we knew
Three-prime truth in the residue
PREM to POEM, the edges align
Like hidden footprints in a straightening line
And a warning turns to hope in real time
Final Chorus
Four ends, one signal, rising from the noise
A wider field of clues, a steadier voice
We don’t need the whole storm to know what it means
Just the way it breaks, and the shape between
Four ends, one signal—now we can see
