Soldadito is the diminutive form of "soldado" (soldier), meaning "little soldier." This word is interesting because it adds a layer of vulnerability and perhaps even a touch of irony to the image of a soldier.
In the song, Rels B sings about being "el soldadito marinero" (the little sailor soldier) of the island. This phrase evokes a sense of being a protector or a fighter, but with a hint of youthfulness or a less imposing stature, making it a unique and memorable image within the lyrics.
Rels B, an artist from Spain, brings us "EL MUNDO X TI," a song that really digs into the feeling of being let down by others while also dealing with personal heartbreak. He starts by talking about people who want to be something but can't quite get there, or maybe they just don't put in the effort: "Todos quieren ser / Quieren ser, pero ellos son, quiero y no puedo / O tal vez no meten como hay que meter" [Everyone wants to be / They want to be, but they are, I want to and I can't / Or maybe they don't put in the effort like they should]. He sees through those who pretend to be friends, just waiting for others to succeed so they can benefit: "Quieren dárselas de amigos, de sinceros / Esperando el brillo de otros pa' comer" [They want to act like friends, like they're sincere / Waiting for the shine of others to eat].
Amidst this frustration with others, Rels B also shares a very personal and vulnerable side. He mentions having many dreams and crying a lot, which he feels makes him more genuine: "Tengo sueños, no se cuentan con los dedos / Lloro mucho, y en verdad, me hace sincero" [I have dreams, they can't be counted on fingers / I cry a lot, and in truth, it makes me sincere]. The repeated line "Llorando en mí, pensando en ti" [Crying in me, thinking of you] really hits hard, showing a deep sadness connected to someone he lost. He even says, "Dejé el mundo por ti" [I left the world for you], which is such a powerful way to express how much he gave up for this person, only to find himself lost now that they're gone: "Ya no estás, me perdí, dejé el mundo por ti" [You're no longer here, I got lost, I left the world for you]. It's a song about navigating a world full of fake people while also grappling with a profound personal loss.
