Contentura is a less common, more colloquial word for 'joy' or 'happiness' in Spanish, often carrying a sense of simple, unadulterated delight. While alegría is more standard, contentura has a charming, almost childlike quality to it.
In the song, the line "Ahí llegó y trajo la contentura" (There it arrived and brought the joy) suggests that something or someone has brought a pure, infectious happiness, making it an interesting and memorable word choice that stands out from more common synonyms.
In "Albaricoque," Brray describes a powerful experience that completely changes his perspective. He sings about something that he didn't want at first but is now making him fall in love: "Primero no la quería y ya me está enamorando." This feeling is so intense that while his feet are on the ground, his mind is flying high ("Tengo los pies en la tierra y la mente está volando").
This song uses clever metaphors to talk about this intoxicating feeling. Brray describes it as something that brings happiness ("contentura"), makes him see colors on a gray day, and tempts him to cause a little trouble. It's a fleeting pleasure that costs money ("La baby no es free"), but he's completely captivated. The lyrics paint a picture of a wild, euphoric state, like being an acrobat who never falls, all while feeling on top of the world.
