Confesarte means "to confess to you." It's an engaging word because it immediately suggests a deep, personal revelation.
In the song, the artist wants to confess his true feelings, moving beyond a casual relationship to something more serious and traditional, "como antes" (like before). This word sets the stage for the song's central theme of wanting to return to a more sincere and profound kind of love.
Have you ever wished love was a little more old-school? Llane's "Como Antes" [Like Before] is all about that! He's inviting someone out, ready to confess something important: he's tired of just having a lover. He says, "Hace mucho dejé de querer algo más que a una amante, porque nadie me daba un motivo para intentar" [A long time ago I stopped wanting anything more than a lover, because no one gave me a reason to try]. But that all changed when he met this person.
He wants to make them feel things they don't usually feel anymore, bringing the past into the present. Llane wants to fall in love "como antes" [like before], the way their parents did, when love was "mucho más interesante" [much more interesting]. He remembers a time "Cuando el amor era mucho más interesante, cuando te abrían la puerta, todo de forma correcta" [When love was much more interesting, when they opened the door for you, everything in the correct way]. He's talking about a time when things weren't so fast, when you had to ask permission, and when talking was more important than dancing or even sex. He even offers to dedicate a bolero to show his feelings. It's a sweet, nostalgic look at wanting a deeper, more traditional kind of romance.
