Compe sosa is a slang phrase that literally translates to "boring competition." It's a clever and somewhat boastful way to describe rivals who aren't a challenge.
In the song, Big Soto uses this phrase to assert his dominance in the music scene, implying that his competitors are so uninteresting and unthreatening that he feels like a legendary figure among them. It's a memorable phrase that captures the artist's confidence and swagger.
Big Soto and Eladio Carrión spend “EL FAVORITO DE MAMI” keeping score on how far they've come, and the hook says exactly what the score means: “Pa'l carajo el number one, me conformo con se' el favorito de mami” [To hell with number one, I'm happy being mom's favorite]. Chasing a title matters less than staying close to the person who mattered before any of this did. Everything else is proof of the distance travelled — “Yeah, yo fui de Old Navy pa' Louis brincamo', Versace y Armani” [Yeah, I went from Old Navy to Louis, we jumped straight to Versace and Armani] tracks the closet, and by the time he lands in Buenos Aires it's “me reciben como en la Bombonera a Cavani” [they welcome me like Cavani at the Bombonera].
The Venezuelan pride sits right next to the passport stamps. “Pero yo soy la trampa internacional” [But I'm the international trap] turns a hometown hustle into something that plays everywhere, and “México me quiere, me siento local” [Mexico loves me, I feel like I belong] says the same about a country that isn't even his own. Under the Cognac and the Cadillac, “el favorito de mami” is still the only title either of them is chasing.
