Arrebata comes from the verb arrebatar, which literally means 'to snatch away' or 'to carry away forcefully'. However, in a romantic context, it often means 'to overwhelm', 'to captivate', or 'to enrapture'.
In this song, CNCO sings, "Y hay algo en ti que me arrebata" (And there's something about you that overwhelms me/carries me away). It beautifully conveys a powerful, irresistible attraction, suggesting that the singer is completely swept off his feet by the person's charm. It's a more intense and poetic way to express being captivated than common verbs like 'gustar' or 'encantar'.
This song is all about that feeling when you see someone across the dance floor and know you have to talk to them. The singer is completely obsessed, admitting, "Soy yo el que no para de llamarte" (I'm the one who can't stop calling you) because he can't get this person out of his head. He's already daydreaming that she's falling for him too, telling her, "Tú me tienes loco, loco" (You have me crazy, crazy).
His big plan? Get the DJ on his side. He repeatedly asks the DJ to play her favorite song, "una para que se mueva y se luzca" (one so she can move and show off). The goal is simple: he wants her to dance "solo conmigo" (only with me). He hopes that as they dance, they'll start falling for each other. He's pretty confident it's working, noting, "Pero tu mirada no me engaña" (But your gaze doesn't fool me).
