The song "A Lo Mejor" by Banda MS de Sergio Lizárraga is about a man who is struggling to let go of a past love. He admits that he may never forget her and that he often thinks about her. He also confesses that he sometimes calls her at night, even though she may not answer. The singer feels like he is nothing without her and questions whether he was truly important to her. Despite her telling him that being with him was not worth it, he still holds onto the hope that she might realize their love was genuine. The song portrays the complexity of relationships and the difficulty of moving on from someone who was once very important to you.
