Ulices Chaidez's "Que Bonito" is a super sweet song all about being head-over-heels in love! He starts by admiring his beloved's eyes, saying they remind him of "las estrellas del cielo" [the stars in the sky]. Then he moves on to their lips, declaring that their kisses are "lo mas bonito que existe en la vida" [the most beautiful thing that exists in life]. It's clear he's completely smitten!
He can't get enough of their laugh, admitting he starts to tremble just being "cerquita" [close] to them. Their whole body "completamente me hipnotiza" [completely hypnotizes him].
