Impregnarte literally means "to impregnate you," but in this context, it's used more broadly to mean "to fill you with" or "to saturate you with."
In the song, the artist sings, "Quiero impregnarte de nuevo con mi fragancia" (I want to impregnate you again with my fragrance). This line uses the word metaphorically to express a strong desire to leave a lasting impression and presence, not in a literal sense, but by enveloping the other person with their scent and essence.
Agus Padilla's "Oh Na Na" is all about that late-night, can't-get-you-off-my-mind feeling! It kicks off with her checking her phone at 3 AM, seeing notifications, and realizing it's late but she really wants to see someone. She's got this message that says, "Desde que lo hicimos no me olvidas" [Since we did it, you haven't forgotten me], and that's all the encouragement she needs.
She's ready to repeat what they did after a party, feeling like she's "volando sin gravedad" [flying without gravity] even without smoking! She wants to get close again, calm their desires, and go "a todas sin miedo" [all in without fear]. She asks them not to leave her "sin tus besos" [without your kisses] because she can't hold back anymore. It's a fun, direct song about wanting to rekindle that spark and not being shy about it!
