“De Las Dudas Infinitas” is a tender confession wrapped in Supersubmarina’s indie-rock warmth. The singer addresses his “pequeña de las dudas infinitas” (little one with endless doubts) and reassures her that, despite past mistakes and the time they have already lost, his devotion is unbreakable. He promises to wait for her “mientras viva”—for as long as he lives—because no one dreams of her the way he does, and no punishment on Earth compares to how much he misses her. The moon itself becomes a comforting guardian, a soft light that will never dim and will always watch over them.
At its heart, the song is about patience, forgiveness, and steadfast love. The narrator admits his faults, offers friendship as well as romance, and pleads with her not to let fear erase what they share. It is a message of hope: even when doubt feels infinite, genuine love remains a steady beacon, guiding both hearts back to one another.
