Astucia translates to "cunning" or "shrewdness." It's an interesting word because it describes a cleverness often associated with trickery or slyness.
In this song, the singer declares, "Porque contigo la astucia se me fue de vacaciones" (Because with you, my cunning went on vacation). This line playfully suggests that his usual cleverness or strategic thinking disappears when he's with this person, implying he's so smitten that he drops all pretenses and simply acts on pure desire.
Have you ever been so smitten with someone that you just can't hide it? That's exactly the vibe Alejandro Santamaria is giving us in "Qué Tal." He opens up by basically saying, "Sorry if it's obvious, but your mouth and that kiss are to blame!"
He's not shy about what he wants either, asking, "Dime qué tal, qué tal si mañana vuelvo a verte?" [Tell me what's up, what if tomorrow I see you again?]. He's hoping for a little luck to turn one night into many, even joking about needing a "visa pa' ir debajo de tu ombligo" [visa to go under your belly button]! It's a fun, flirty song about being completely captivated and wanting to see where things go, without any games or hidden agendas.
