Madrugada refers to the very early hours of the morning, typically between midnight and dawn. It's a beautiful and evocative word that captures a specific, often quiet and reflective, time of day.
In the song, the artist uses it to describe the time when he's still awake, unable to stop thinking about someone. He says, "O más bien dicho, madrugada, no dejo de pensar en ti" (Or rather, early morning, I can't stop thinking about you), highlighting the deep thoughts and emotions that surface during these solitary hours.
Have you ever been up late, when it's super quiet, and your mind just starts racing? That's exactly where Alfredo Olivas takes us in "A Estas Horas." He's awake in the middle of the night, when "todo es tan incierto" [everything is so uncertain], and even though it feels like the sun should be coming up, the crickets are still singing. He should be asleep, but for some reason, he's wide awake.
And guess who he's thinking about? You guessed it – an ex! Her memory just pops up "de la nada" [out of nowhere]. He wonders if she's sleeping, or if she's also talking to her pillow. He really doesn't want the dawn to break "Sin por lo menos escuchar tu voz" [Without at least hearing your voice]. He's hoping that maybe, just maybe, at this late hour, she might even fall in love with him again. He wants her to forget the past, because he's a "hombre nuevo desde tu adiós" [new man since your goodbye]. It's a really honest look at those late-night thoughts when you're missing someone and hoping for a second chance.
