Poderío translates to "power," "might," or "authority." It's a much stronger and more poetic word than the common word for power, poder.
In the song, Ozuna sings, "Que la música tiene poderío," to say that the music has an irresistible force and influence. This single word perfectly captures the theme of the song: the commanding power of the rhythm that makes everyone lose control and dance all night.
This song is a pure celebration of the weekend! Ozuna sets the scene perfectly: a woman is tired of her boring weekly routine, or "la monotonía no quiere seguir" [she doesn't want to continue in the monotony], and just wants to go out. He sees her and is immediately captivated, inviting her to dance because "la noche solamente comienza" [the night is just beginning]. It's all about that moment when you hit the dance floor and forget everything else.
The whole point is to keep the party going. Ozuna repeats the command "Síguelo bailando, que la música no pare" [Keep dancing, don't let the music stop] like a mantra for a perfect night out. He describes how the woman he's watching solves all her problems through dance: "No tiene problema si lo resuelve bailando" [She has no problems if she can solve them by dancing]. It's a fun, simple anthem about letting the music take over and wishing the night would never end.
