Remontar is a versatile verb that can mean "to ascend," "to overcome," or "to go back up." It's a less common word in everyday conversation, making it stand out.
In this song, the singer uses it to express a desire to "remontar a las estrellas" (ascend to the stars) and escape with their love to a place where no one can judge them. It beautifully conveys a sense of aspiration and overcoming societal judgment.
This song is a total declaration of love that doesn't care what anyone else thinks! The singer is completely smitten, even admitting, "es más vergonzoso solo porque tu amor es mi espiral" [it's more embarrassing just because your love is my spiral]. It sounds like their love is so intense it's almost overwhelming, but in a good way.
They're well aware that people are talking about them, saying "hablan de los dos que es un escándalo" [they talk about the two of us, that it's a scandal], and even that the singer is being called names for giving their love. But their response is clear: "no hagas caso de la gente sigue la corriente y quiéreme más" [don't pay attention to people, go with the flow and love me more]. It's a bold and romantic message about choosing love over societal judgment, with a dream of taking their beloved to the stars "a donde nadie nos viera" [where no one would see us].
