"Vueltas" is a guy talking straight to an ex who keeps pretending she's fine. The title means "turns" or "spins", and the opening line says she does muchas vueltas (lots of laps) through his conscience. She's stuck in his head, and he is pretty sure he's stuck in hers.
He doesn't buy her act. She lives presumiendo (showing off) the life she leads, but escuchas mi nombre y sabes que eso te afecta (you hear my name and you know it gets to you). Then comes the cheeky invitation: Salte de ese antro, mejor vámonos a casa (get out of that club, let's just go home). Antro is Mexican slang for a nightclub, usually a slightly rough one, and te me enfiestas means she goes out partying, with that little me making it sound like she's doing it to spite him.
The second half gets more honest. Hice mis decisiones y para atrás ya no hay vuelta (I made my choices and there's no going back), he admits, but he still signs off believing nuestras almas son gemelas (our souls are twins). It's confident, a bit stubborn, and very easy to sing along to.
