"Facetime" is LIT killah stuck in a long-distance relationship and very, very done with it. The chorus is the whole complaint: "Ya me cansé de esperar de verte solo por FaceTime" (I'm tired of waiting, of only seeing you on FaceTime), "y no poder tocarte, muero por besarte" (and not being able to touch you, I'm dying to kiss you). It is a love song where the screen is the villain.
The verses are pure late-night texting energy. He sleeps "con el fono al lado de la cama" (with the phone next to the bed), and fono is casual Southern Cone slang for the phone. "La distancia no quiere decir que no" (distance doesn't mean no) is his stubborn optimism, and "Solamente nos sentimos cerca por la webcam" (we only feel close through the webcam) is the reality check. He drifts into English the way a lot of Argentine trap does, with "I see you, honey" and the closing wish, "Quiero que esta vez sea face to face" (I want it to be face to face this time). The song gets openly steamy in places, so expect a few lines that are more bedroom than romance.
For learners, it is a nice workout in quiero que plus the subjunctive: quiero que terminemos, quiero que esta vez sea, que despertemo' juntos (that we wake up together), where the dropped final s is very typical of how it is actually sung.
