Song is a regular part of the lives of the little ones, from the family environment to school, where it becomes one of the most used tools in early childhood education due to its educational potential. Therefore, it is important to analyze in detail the content of the songs listened to by the youngest. This research starts with the hypothesis that children at an increasingly premature age listen to and play songs with sexist content, which may affect their future behavior. To confirm or refute it, a mixed methodology was used, using the questionnaire as instruments applied to 116 parents from 4 educational centers in A Coruña, and interviewing 7 teachers. The results indicate that schoolchildren are mainly exposed to musical genres not appropriate to their age, both in their family environment and in the classroom to a lesser extent, concluding that they listen to and play songs with sexist content, which may affect their future behaviors.
