Lyrics:
Verse 1
Long nights, bright screens, we counted tiny traces
Sperm heads held a whisper folded in their faces
Fragments of a message, shifting with the clock
A quiet cliff appeared where numbers stopped

Pre-Chorus
Aging cliff in the middle years, a sudden bend
Longer fragments rising, the shorter ones descend
Mitochondrial echoes answering the genomic trend

Chorus
Tiny codes louder than we imagined, carrying weight
They tune the dawn in ways we only start to translate
From small letters of RNA, a future's slate
Tiny codes, tiny codes

Verse 2
We gave an age-mimic and watched the letters speak
Stem cells moved toward metabolic and neurodegeneration peaks
Not a fate declared, but a compass shifting range
A map of mystery traced inside a small exchange

Bridge
The how remains a shadow, origins still untold
Synthetic notes lack old marks that nature holds
But these head-specific patterns rise as candidate signs
We keep the questions close and follow the lines

Final Chorus
Tiny codes louder than we imagined, carrying weight
They tune the dawn in ways we only start to translate
Across mice and humans, a conserved, shifting line
Tiny codes, tiny codes — a key to read the time
