Amaral, the Spanish duo, open this one in a dark place: "Siento que mi alma se encuentra perdida" (I feel my soul is lost), a state so confused that "se junta la noche y el día" (night and day run together). Then someone shows up, and just seeing them sends "terremotos" (earthquakes) through the singer's whole body. Earthquakes for a crush is a big image, and the song means it.
The chorus is the whole point: "Haces que se vaya mi melancolía, me devuelves de nuevo a la vida" (you make my sadness go away, you bring me back to life). That is the resurrección of the title, and the last word of the song is that one word on its own.
There is a sweet twist in the middle: "Antes de llegar siquiera a conocerte, mucho antes ya te quería" (before I even got to know you, I already loved you long before), loving the person "como algo inalcanzable" (like something out of reach). Near the end the song turns outward: "Quiero un mundo nuevo" (I want a new world) and "Mi corazón no lo compra el dinero" (money doesn't buy my heart).
Learner tip: haces que se vaya is hacer que + subjunctive, "you make (something) go". You will hear that pattern everywhere in Spanish.
