Desequilibrado translates to "unbalanced" or "off-kilter". It's a more descriptive and less common word than simply saying "sad" or "confused", making it stand out.
In the song, the artist sings, "creo que estoy óptimamente desequilibrado" (I think I'm optimally unbalanced). This intriguing phrase suggests a state of being perfectly imperfect or finding a strange balance in his disarray after a breakup, adding a unique layer to his emotional state.
Alfonso El Pintor's "Mensajitos Al Amanecer" drops us right into that restless pre-dawn feeling when you can't sleep and your mind just won't quit. Our singer is literally "dando vueltas en la cama sin poder dormir" [tossing and turning in bed, unable to sleep], feeling a bit off-kilter and out of sync with the world. It's that weird time when memories of the night before, and maybe a certain someone, come flooding back.
He's getting those "mensajitos al amanecer" [messages at dawn] – you know the ones, maybe a little out of place, a little confusing. Even though he's trying to distract himself by going out with friends, he can't stop thinking about this person. He even imagines them hearing this very song on the radio and thinking about him getting those early morning texts. It's a relatable look at how someone can really get under your skin, making you miss them so much you can't sleep, even when they're not responding.
