Disparates translates to "nonsense" or "absurdities." It's a fun and slightly whimsical word that isn't heard in every song, making it stand out.
In the lyrics, Charles Ans sings, "Sabes, estoy cantando disparates" (You know, I'm singing nonsense). This line offers a glimpse into the artist's self-awareness and perhaps a playful acknowledgment of the emotional or rambling nature of his thoughts and feelings expressed in the song.
Charles Ans's "Andrómeda" is a heartfelt plea for a kiss from a woman he's completely captivated by. He calls her the "gobernante de mis ojos Andrómeda" [ruler of my eyes, Andromeda], showing just how much she dominates his thoughts. He's lost in her gaze and her walk, feeling it's unfair she judges him without giving him a chance. He even admits to singing "disparates" [nonsense] to try and fill the void she's left, confessing she's like a stampede hitting him.
He looks back on their past, remembering how she was his "condena" [sentence] and how he once felt like a king without a queen. But time has passed, and now he's gone from missing her to hearing her voice again, still hoping for an excuse to be together. Despite the longing, there's a hint of moving on, as he sings about a "ciclón durmiendo en mi cama" [cyclone sleeping in my bed] and waking up without a plan or a migraine. He's still watching her, asking her to love him now and forget tomorrow, even as he acknowledges he's just a "pobre diablo" [poor devil] paying his dues after she left him for being jealous and crazy. Ultimately, she's his Andromeda, his anesthesia, a significant part of his life.
