Meteorito literally translates to 'meteorite', making it a highly unique and dramatic word to find in an emotional song about a failed relationship.
Morad uses it to create a brilliant metaphor when he sings, "yo quería darte la estrella y acabó todo en un meteorito" (I wanted to give you the star and it all ended in a meteorite). He plays with space vocabulary to explain that his beautiful, romantic intentions ultimately crashed down into a destructive disaster.
This song is a classic breakup anthem, but with a twist from the streets. Morad and his friends are calling out someone who wasn't there for them when things were tough. The main point is right in the title: "No estuviste en lo malo, dime, ¿por qué en lo bonito?" (You weren't there for the bad, tell me, why [should you be here] for the good?). He remembers wanting to give this person everything, saying "yo quería darte la estrella y acabó todo en un meteorito" (I wanted to give you the star and it all ended in a meteorite). It's a great line about a dream crashing and burning.
But here's where it gets interesting. For someone who claims "Hace tiempo que de ti yo nada necesito" (For a while now, I've needed nothing from you), he spends the whole song thinking about her. He admits, "Llevo dos meses pensándote" (I've been thinking about you for two months) and can't stop himself. He tries to act tough, like a lone wolf whose "huellas son como de un lobo" (footprints are like a wolf's), but the pain is obvious. He's stuck between wanting to forget and being unable to.
