Desbocarme literally means "to unbridle oneself" or "to run wild," often used for horses. It's a vivid and less common verb that implies a loss of control or a passionate outpouring.
In the song, the singer uses it to express his intense desire to shout his feelings to the wind, despite it not being his usual custom. He says, "Y si te encanta voy a desbocarme gritándolo al viento" (And if you love it, I'm going to unleash myself shouting it to the wind), showing a powerful emotional release.
This song is a fascinating journey through the mind of someone trying to move on from a breakup, but it's not as easy as they pretend! The singer starts by giving a sarcastic "new applause for hurting me" and vows that their life isn't over. They even declare, "Hoy te confirmo que algún día voy a ser feliz" [Today I confirm that someday I will be happy], even though they admit, "Aunque me cueste porque aún no te he olvidado" [Even if it costs me because I still haven't forgotten you].
What's really fun is how the singer keeps trying to be strong and silent, saying things like "Yo siempre acostumbro que cuando me hieren siempre hago silencio" [I always make a habit of being silent when I'm hurt]. But then, they completely give in! They say, "Pero si te encanta, está bien voy a decirlo / Que yo te extraño, te extraño, te extraño, te extraño aún" [But if you love it, it's okay, I'm going to say it / That I miss you, I miss you, I miss you, I still miss you]. It's like they can't help but shout their feelings to the wind, even though it's "No es mi costumbre" [It's not my custom]. It's a really honest and relatable look at how hard it is to let go, even when you know you should.
