Extravagantes is the plural form of "extravagant": something flashy, lavish or out-of-the-ordinary.
Camilo sings that even after traveling to the most sitios más extravagantes (most extravagant places), his partner’s body is still his favorite spot. The word injects flair and sophistication, making it a memorable term for learners while hinting at the song’s romantic message that luxury can’t compete with true love.
Colombian singer Camilo is known for his romantic and happy songs, and "Favorito" is a perfect example! He starts by listing all the amazing things he's done in his life: he's eaten at the fanciest restaurants and traveled to the most extravagant places. But after all that, he had a big realization. He sings, "Descubrí, que tu cuerpo es mi lugar favorito / Y tu boca mi comida favorita" (I discovered that your body is my favorite place / And your mouth is my favorite food). It's a super direct and sweet way of saying that no luxury in the world compares to being with the person he loves.
He goes on to say that it took him a while to figure this out. He had to travel the world just to realize the perfect person was right beside him all along. He tells her, "Tú eres perfecta, sin el noventa sesenta noventa" (You are perfect, without the 90-60-90), rejecting a common body standard and loving her for who she is. The whole song is a declaration that they are exactly what the other needs, a perfect match found in simple, everyday love rather than in fancy experiences.
