[Verse] Beneath the city’s veins, the shadows breathe, Steel serpent waking, grinding underneath. Whispers in the dark, a pulse I chase, Echoes riding wheels, a cold embrace. [Pre-Chorus] Heartbeat humming low, the rails command, Draw me deeper in where no light lands. [Chorus] Feel the thunder in the silence, rise and fall— Second heartbeat pounding through the underground call. Darkness sings a secret song I can’t deny, Racing, chasing through the veins where shadows lie. [Verse] Tunnels twist like fate, a labyrinth of sound, Ghosts of journeys past, beneath the ground. Glossy lights flicker, like truth in disguise, Every breath this train takes, a new surprise. [Pre-Chorus] Heartbeat humming low, the rails command, Draw me deeper in where no light lands. [Chorus] Feel the thunder in the silence, rise and fall— Second heartbeat pounding through the underground call. Darkness sings a secret song I can’t deny, Racing, chasing through the veins where shadows lie. [Bridge] Through the hum and grind, I’m alive, I’m free, A siren’s voice in the depths, calling out to me. Glossy notes soar high, cut through the night, In this tunnel’s heartbeat, I find my light. [Chorus] Feel the thunder in the silence, rise and fall— Second heartbeat pounding through the underground call. Darkness sings a secret song I can’t deny, Racing, chasing through the veins where shadows lie. [Outro] Pulse beneath the city, never still, Second heartbeat echoes, always will.
