In "Date Cuenta" (Wake Up / Realise It) Arcángel is the guy waiting in the wings while the woman he wants stays with someone who ignores her. The chorus is a little revenge fantasy: "Me imagino cuando abra los ojos y no te vea" (I imagine when he opens his eyes and doesn't see you), and he goes online to check, only to find "conmigo la foto que tú postea'" (the photo you post is with me). The dropped "s" in postea' and to' (todo) is pure Puerto Rican speech, so get used to hearing word endings swallowed.
The verse is where he gets playful. He tells her "tú eres de Marte y yo de Júpiter" (you're from Mars and I'm from Jupiter), says her body beats the art of Picasso and Da Vinci, and calls her "agua bendita, mi cantimplora" (holy water, my canteen), which is a funny line to put in a love song. Then he invites her to escape to Bora Bora. Under the jokes he's serious: "Yo sé que a diario tú lucha' porque él no te escucha" (I know you struggle every day because he doesn't listen to you). It's a good song for practising the subjunctive after cuando and si yo fuera.
