Gelosia means 'jealousy'. While it's a common emotion, its inclusion in this playful song about Mamma Maria, a fortune teller, makes it particularly interesting.
The lyrics mention, "Ha un filtro contro la gelosia" (She has a filter against jealousy). This suggests a magical remedy or charm to ward off negative feelings, adding a whimsical and intriguing element to the word in the context of the song's narrative.
Have you ever wanted a fortune teller who only tells you good news? Meet Mamma Maria! The song introduces us to this mysterious woman in a room with a white cat with blue eyes and the smoke from candles. She seems to have a solution for everything, with a "filtro contro la gelosia" (a potion against jealousy) and a "ricetta per l'allegria" (a recipe for happiness). She reads your destiny in the stars and promises to tell you "solo cose belle" (only beautiful things).
The singer is dying of curiosity and has some big questions for Mamma Maria. First, they wonder what the future holds, hilariously wishing they could be a king to make an American blonde fall in love with them, or else they'll turn her into a frog! But the real question is about a specific love. They ask Mamma Maria for the truth: "Voglio sapere se questo amore / Sarà sincero" (I want to know if this love / will be sincere). Even though they admit, "Non ho una lira" (I don't have a lira/any money), they want to buy the sky and the moon for their beloved. All they need is a little bit of luck from Mamma Maria.
