Embustero translates to "liar" or "deceiver". It's a strong, evocative word that carries more weight than a simple "mentiroso" (liar), suggesting a habitual or cunning deceiver.
In "Azúcar Amargo", Fey uses this word to describe a lover who is both sweet and bitter, an angel and a devil. Calling him a "maldito embustero" (damned deceiver) highlights the deep betrayal and confusion she feels, making it a memorable and emotionally charged word in the song.
“Azúcar Amargo” is Fey’s punchy pop confession about loving someone who tastes like candy one second and poison the next. The Dutch singer catches her partner acting distant, so she fires off questions and demands the truth: Why don’t your eyes shine like yesterday? She feels the relationship slipping, yet she is still hypnotized by the “music” of his kisses. The chorus turns that feeling into the catchy oxymoron azúcar amargo - sweet sugar mixed with a bitter after-taste.
As the beat bounces along, Fey wrestles with a tug-of-war between passion and pain. She calls her lover an “angel and a devil,” a thrilling box of surprises that keeps her hooked even while she suspects betrayal. Faced with the possibility of another woman, she steels herself to end things “en sano” – cleanly – if the rumors are true. In the end, the song is a neon-lit diary entry about the highs of irresistible attraction and the lows of realizing you might be losing the person you adore. Listeners can dance to the upbeat groove while feeling every twist of Fey’s bittersweet emotional roller-coaster.
