Balearico refers to something or someone from the Balearic Islands, a Spanish archipelago in the Mediterranean Sea. It's a unique and specific term that immediately grounds the song in a particular cultural and geographical context.
In the song, Rels B, who is Mallorquín (from Mallorca, one of the Balearic Islands), uses this word to proudly declare his identity and ownership of the local culture, singing "Balearico, son nuestros los mares" (Balearic, the seas are ours). It's a strong statement of regional pride and a less common word than general descriptors of Spanish identity.
Rels B, a Spanish artist, invites us to the Balearic Islands in "Balearico," where the sun is hot and life is good. He paints a picture of a relaxed, luxurious lifestyle, but with a down-to-earth twist. Instead of champagne, they're drinking wine, and paella on the boat "sabe mejor" [tastes better]. He's with a Colombian woman who "tiene el sazón" [has the flavor/spice], making her stand out from the rest.
He talks about being a "boss" on the island and how true wealth isn't about how much you earn, but about "no tener responsabilidades" [not having responsibilities]. He's got houses in Mallorca and Medellín and hopes his plans work out, wishing for a daughter who looks like his partner. Rels B also flexes a bit, talking about his rise to pop stardom and how his style is unique, saying "Yo no soy de Miami, yo soy mallorquín" [I'm not from Miami, I'm from Mallorca]. He cherishes his family, health, and money, and enjoys the freedom of life, even if it means calling the dealer sometimes to "amanecemos" [stay up until dawn]. It's all about living genuinely and enjoying the moment, because "mañana quién sabe" [who knows about tomorrow].
