The aim of this research was to explore gender differences in musical taste and the mediating role of functions of music between gender and musical taste. The research included 740 Croatian and Slovenian students. The results confirmed the existence of gender differences in both musical taste and functions of music. Females preferred the Reflective-Complex musical style, while males showed greater preferences towards Intense-Rebellious style of music. There was no significant gender difference in preferring Traditional and Contemporary Ethno or Energetic and Rhythmic musical style. With regard to the functions of music, there were no significant differences between males and females in identity/culture and background and focus /concentration functions of music. Males assessed political attitudes as a more important function of music than females, while females assessed all other functions of music higher than males did. A complete mediation effect of functions of music was established for gender and Reflective-Complex and Slo-Yugo Pop musical style.
