Julio Iglesias's song "Momentos" is about the fleeting nature of time and the importance of cherishing the special moments of our lives. The lyrics tell the story of a couple who spend their nights talking and dreaming about their future together and how to make the most of their time. Even in small arguments, they always end their nights with a kiss and a promise to be together again. As time passes, the song reflects on the memories they shared and how little remains of the past. The couple had promised that nothing could separate them, but as life goes on, they realize that some things are out of their control. Despite this, they reminisce about the times they spent together, letting their senses fly and dreaming of a future that now seems unreachable. Ultimately, the song is a reminder to appreciate the fleeting moments that make up our lives because, in the end, they are all we have. It speaks to the universal experience of nostalgia and the bittersweet feeling of looking back on memories we can never relive.
