Tormento translates to "torment" or "anguish." It's a strong, evocative word that immediately conveys deep emotional distress.
In the song, the lyric "mi persona se duerme un tormento" (my person falls asleep a torment) suggests that the singer's very being is consumed by an internal struggle or pain, even in sleep. This dramatic imagery makes the word stand out and adds a layer of intensity to the romantic narrative.
Alex Cuba's "Di Que Me Amas" is a sweet, dreamy song about being completely captivated by someone. He sings about how just a glance from this person makes him want to steal a kiss, and how their simple "good morning" affects his feelings. It's like his whole being goes quiet, a "tormento" [torment] when they speak, because he's so overwhelmed he can't find the words.
He describes seeing their hair fly in the wind and how easily a thousand glances from him fall on their silence. This person's movements cut through hearts like scissors, and their perfection is so intense it almost scares him, making him wonder if it's all a dream. He's just dying of desire, wanting them to "Di que me amas" [Say that you love me] with just a look that reaches his heart.
