Perdiendo la cabeza literally translates to "losing the head," but it's a very common Spanish idiom that means "losing my mind" or "going crazy."
In this passionate song, Carlos Rivera repeats this phrase to express how he's being driven mad by his intense feelings for someone. It's a dramatic and memorable way to describe the all-consuming, overwhelming power of love.
Have you ever fallen so hard for someone after a single night that your brain completely shuts off? That is the exact chaos Mexican singer Carlos Rivera, Becky G, and Pedro Capó dive into here. The track is built on an irresistible memory of dancing close until lips meet: "esa boquita fue mi boquita" ("that little mouth was my little mouth"). One person warns that another kiss will seal the deal ("Con otro beso tuyo me enamoraré" [With another kiss from you, I will fall in love]), and instead of pumping the brakes, the speaker goes straight in for it. Now, separation feels unbearable. There is a great everyday idiom right in the chorus: "he perdido la cabeza" literally means "I have lost my head," which is how Spanish speakers say they are going completely crazy over someone.
From there, the drama gets delightfully over the top. People in the street try to offer sensible advice, saying love sickness will not kill you ("Dicen en la calle que no mueres de eso" [They say on the street you don't die of that]), but the singer dramatically rejects common sense: "si no me muero" (if not, I'll die). The lyrics mix sweet longing with steamy flashbacks of intimate promises, like whisperings of "Vamos a hacer cositas todo el día" ("We are going to do little things all day"). When someone is that gorgeous ("Tanta belleza" [So much beauty]), pride goes straight out the window, leaving a heart loudly begging for their lover to come back.
