Bilirrubina refers to "bilirubin", a yellow pigment found in bile. It's a very unique and memorable word, especially for a song title!
In this iconic merengue song, Juan Luis Guerra uses "bilirrubina" metaphorically to describe the overwhelming physical and emotional symptoms of being deeply in love. He humorously compares the intense feelings of love to a medical condition, where his love for someone causes his "bilirubin" to rise, making him feel sick with passion. This creative and unusual comparison makes the word stand out and perfectly captures the song's playful yet ardent tone.
Have you ever been so in love it feels like you're actually sick? That's exactly what Juan Luis Guerra is singing about in "La Bilirrubina"! He describes a hilarious scenario where he's rushed to the infirmary because of his love, even though he doesn't have insurance. The doctors try everything – "me inyectaron suero de colores" [they injected me with colorful serum], "me sacaron la radiografía" [they took my X-ray] – but nothing works. They diagnose him with "mal de amores" [love sickness] just by seeing his heart beat!
He even jokes that science is useless and only his lover's kisses can cure him. He begs his love to "inyéctame tu amor como insulina" [inject your love into me like insulin] because his "bilirrubina" [bilirubin] has gone up, making his face yellow! He sings that this feeling "no lo quita la aspirina, no, ni un suero con penicilina" [aspirin won't take it away, no, nor a serum with penicillin]. It's a love that "contamina" [contaminates] him, but in the best way possible! It's a really fun and catchy song about being completely overwhelmed by love.
