When we think about the deeper meaning of the song, 'No Soy El Aire' is a Thalia's song which speaks of a love-life that has faded with time, and it uses the metaphor of a soap bar which melts away gradually with its use. The lyricist outlines the realization that the person is not a must-have in the partnership, accepting that the other person will continue living, as if nothing has happened, after the departure, indicating the tacit acceptance of moving on and letting go. The majority of the no soy el aire lyrics portray the themes of heartbreak, angst, reflection, despair and solitude. In contrast, the song emphasizes the necessity of ending a relationship, self-discovery and moving on. The lyrics speak of love and breakups, which could be seen as requiring parental supervision for the very young ones. Although there is no vulgar or violent content, still the emotional themes might not be appropriate for every child.
