Have you ever wanted a second chance so badly you'd promise to change everything? That's the heart of "Buenos Genes". Rels B kicks off the song with a powerful vow: "I swear that from today on, I'm not going to hurt you." He's looking back at his past, admitting he was like a "blind man wasting time" and that he's no longer the "silly kid" he used to be. Now, he's terrified of losing his love to someone else, pleading with her to believe that this time, he's going to do things right.
This isn't just an apology; it's a love song full of admiration. He's completely captivated by her, calling her "mi gitana" (my gypsy) and marveling at her beauty, saying she's "so beautiful it hurts." The song deepens when DELLAFUENTE adds his part, suggesting their love is a source of true freedom and something unconditional. He hints that they face outside problems or judgment, but he's ready to fight for their relationship, declaring that it would take a serious trial, a "grande el juicio", to ever tear them apart.
