Desvelada describes someone who is sleepless or has been awake all night. It's a more evocative word than simply saying 'awake', implying a state of being unable to sleep, often due to worry or anticipation.
In the song, the lyrics say, "Estás desvelada," suggesting that the person the singer is addressing is awake in the early hours of the morning, perhaps thinking about him or unable to sleep because of the situation between them. This word adds a touch of vulnerability and intimacy to the scene.
Junior H and Jose Mejia's "Suena" is a really direct breakup song. It's about a relationship where there's no room for a third person, and the singer is completely over it. He's not interested in fake explanations or apologies, stating bluntly, "No quiero oír tu falsa explicación" [I don't want to hear your fake explanation] and "Duele decirlo, pero no hay amor" [It hurts to say it, but there's no love]. He even says, "Se te acabó el tiempo, ahora no vales nada" [Your time ran out, now you're worth nothing], which is pretty harsh!
He's ready to move on and be independent, looking to "Vivir la vida un poco mejor" [Live life a little better] in the future. The song's title, "Suena" [It sounds], comes from the image of his guitar playing at five in the morning, a serenade that's actually a goodbye: "Soy el único en el universo / Que se despide con una canción" [I'm the only one in the universe / Who says goodbye with a song]. It's a bold and final farewell, even mentioning past threats and self-harm, but ultimately, he's done with the relationship.
