Trasnoché comes from the verb trasnochar, which means to stay up all night or to burn the midnight oil. It's a more evocative and specific term than simply saying "I didn't sleep."
In the song, the artist uses Trasnoché to set a reflective and somewhat melancholic tone, describing nights spent awake under the stars, contemplating life and dreams. It immediately draws the listener into the intimate, late-night world of the lyrics.
Ulises Bueno's "Trasnoché" feels like a late-night confession from a soul searching for meaning. He sings about staying up all night, "con todas las estrellas encendidas me dormí" [I fell asleep with all the stars lit], and waking up in unknown places with "cicatrices de la lluvia" [scars from the rain] or "cicatrices de lujuria" [scars of lust] on his skin. It's a raw look at a life lived on the edge, where he realizes he only had "honor dinero" [honor, money] and never truly listened to his own desires.
He calls himself a "lobo herido" [wounded wolf] and a "cantor de tren ganas, amigo del alma" [singer of desires, soul friend], someone who never had much but dreams big. He's an "artista importante" [important artist] in his dreams, even if others call him "atorrante" [bum] or think he's "delirando" [delirious]. But he has faith that "un buen día los platos serán lentos" [one good day the plates will be slow] when everyone discovers his madness was actually genius. It's a powerful anthem for anyone who's ever felt misunderstood but held onto their dreams.
