Soltería translates to "singleness" or "the state of being single." It's a less common word than simply "soltero" (single person) and carries a slightly more formal or descriptive tone.
In this song, the artist declares, "Oficialmente andamos en soltería" (Officially we are in singleness), celebrating a newfound freedom after a bad relationship. It's an interesting word choice because it emphasizes the state of being single, rather than just being a single person, making it feel more like a deliberate declaration of independence.
Have you ever gotten out of a relationship and just wanted to celebrate your freedom? That's the spirit of Eden Muñoz's song, "Oficialmente En Soltería" (Officially Single). The singer declares he's finally free and ready to enjoy life, telling everyone, "what will be, will be." He's avoiding any new commitments and asking his friends to invite him out for drinks so he can properly "close the chapter" on his past.
The chorus is a bold announcement: "We are officially single, how lucky I am!" He calls his past relationship just a "scare" and a "bad decision." But instead of looking for a new romance, he says a "drunk has been born" who is now lost in a new kind of relationship: one "with partying and alcohol." It's a fun, anthemic song about embracing the single life, even if it means leaning on a few drinks to get through the breakup.
