Peregrino translates to "pilgrim". It's a word that evokes a sense of journey, devotion, and seeking, which is less common in everyday song lyrics.
In the song, the singer refers to himself as a "flamante peregrino" (flaming/ardent pilgrim) in love. This suggests he is on a passionate quest for love, dedicating himself fully to his beloved, much like a pilgrim on a sacred journey.
Get ready to swoon! Ivan Villazon and Saúl Lallemand's "Inseparables" is a beautiful declaration of undying love and devotion. The singer wants to be with his beloved just like a river is a leader in its swarm, or like parents are to a family. He dreams of being "inseparables" [inseparable] with his love, a poet for her, and a pilgrim in love.
He wants the moon to drink wine and toast with the stars to their pure and sincere love. Even if he could go far away like a lost bird or a pirate searching for treasure, his love is always in his heart, his "estrellita" [little star] when he's alone. He tells other women who might want his affection that he belongs to his love "de día y de noche" [day and night]. He even imagines stealing a ray of light from the heavens and putting it in her gaze so she can light his path wherever he goes. It's a sweet and passionate promise to be together always, through thick and thin!
