This study aims to analyze the effectiveness of using pop folk songs as learning media in improving high school students' mastery of English vocabulary. The method used was quasi experiment with two groups, the experimental class using pop folk songs and the control class using lecture or drilling method. Data were obtained through pre-test and post-test which were analyzed using statistical tests. The results showed that there was no significant difference between the two groups in vocabulary improvement. Internal factors such as the low motivation of students in the experimental class as well as external distractions during the learning process were the main obstacles in the application of this method. Although folk pop songs can provide a more interesting learning atmosphere, its effectiveness still depends on classroom management and student engagement. Therefore, a more varied combination of learning methods is needed so that the results obtained are more optimal. This study provides insights for educators in designing more effective music based learning strategies. Further research is recommended to explore other factors that influence the success of using songs in English language learning.
