Grillete means "shackles" or "handcuffs". It's a powerful, dramatic word that you don't often hear in a love song, making it instantly intriguing.
In the lyric "Yo por ti, tú por mí, que me pongan los grillete'" (Me for you, you for me, let them put the handcuffs on me), it's used as a bold metaphor for a 'ride-or-die' loyalty. It expresses a love so strong that the singers are willing to face any consequences, even being arrested, as long as they are together.
Yo X Ti, Tú X Mí is a playful love anthem where Spain meets Puerto Rico. Over a smooth reggaetón beat, ROSALÍA and Ozuna trade lines that feel like a flirtatious game of ping-pong: “yo por ti, tú por mí” (me for you, you for me). The phrase repeats like a heartbeat, underscoring a pact of mutual devotion. They brag about worldwide success, diamonds, and sold-out shows, yet every boast circles back to the same idea: fame is sweet, but having someone who has your back is sweeter.
Behind the luxury images—“flowers and money,” “tickets and diamonds”—the song celebrates loyalty, chemistry, and the thrill of finding a partner who matches your energy. ROSALÍA bets everything on the lucky number seven if Ozuna will catch her when she falls; Ozuna says he would spend all he has just to see her eyes shine. Together they paint love as a fearless, glitzy adventure where each is willing to risk it all for the other. The message is simple and catchy: when two people commit to lifting each other up, they feel unstoppable… and they can make the whole block dance to their song.
