Aclárate comes from the verb aclarar, meaning 'to clarify' or 'to clear up'. The reflexive form aclararse means to 'clear things up' or 'make up one's mind'.
In this song, the singer is frustrated by his love interest's mixed signals and indecision. He desperately pleads, "Por favor, aclárate" (Please, clear things up), urging her to decide whether she wants him or not. It's a direct and emotionally charged plea that captures the central conflict of the lyrics.
Have you ever been stuck in that frustrating in-between stage with someone? Sebastián Cortés totally gets it in "Aclárate" [Clear Things Up]. He's absolutely smitten, admitting, "me tienes loquito por ti" [you have me crazy for you]. But the person he's singing to seems to be playing games, with "intenciones de jugar con mi cabeza" [intentions of playing with my head].
He's at his wit's end, feeling like he can't move on because they keep pulling him back in. He just wants a clear answer: "Por favor dime que me vaya ya, o dime que me quedo junto a ti" [Please tell me to leave now, or tell me to stay with you]. He's even willing to give everything, saying, "To' lo que haya de mi te daré, to' lo mío tuyo es" [Everything I have I will give you, all mine is yours]. It's a super relatable song about the agony of not knowing where you stand and just begging for some clarity!
