Destilan comes from the verb destilar, which means 'to distill'—the process of purifying a liquid. It’s a very poetic and uncommon word to find in a song.
Beele sings, "Esos ojitos amor destilan" (Those little eyes distill love). He's using this word metaphorically to say that her eyes express a pure, concentrated, and powerful form of love, making it a beautiful and memorable line.
In this song, Beéle is looking for a sign from the universe. He sees the person he likes as his star, asking, "Mi estrella, ¿dónde está mi estrella?" (My star, where is my star?). He hopes that if he sees a shooting star, it will be a confirmation that they are meant to be together. He's so serious about this that he wants to see "Un meteoro a ciento veinte mil millas pa' comprobar / Que vamos a ser tú y yo" (a meteor at one hundred twenty thousand miles to prove / that it's going to be you and me).
But it's not all just waiting for cosmic signs. He's also direct about his feelings and what he wants. He lays his cards on the table, saying, "Habla claro antes de meterle corazón" (Speak clearly before I put my heart into it), asking for honesty before he gets too invested. He even uses modern slang to ask for a kiss, calling it a "colabo'" (collaboration). It's a sweet and hopeful song about wanting to be sure that a new love is real.
