It has been broadly asserted that the getting used to the activity of listening to English songs is a recommended method to enrich students' vocabulary. However, further empirical studies are still needed to relate that with adult EFL learners. Therefore, this study examines the correlation between regular music exposure and vocabulary recognition in adult learners. The subject involved 72 university students. They are chosen randomly from the third semester students of English Teacher Education Department at an Islamic State University in Indonesia. To obtain the data concerning the student's habit and exposure to English songs, this study employs the instruments such as Aural Vocabulary Knowledge Test and a questionnaire. The statistical analysis employed Pearson Product Moment Correlation. The finding demonstrates the correlation between regular exposure to English song and students' vocabulary recognition which is significant. It implies that the habit of listening to English songs contributes to the better level of vocabulary recognition of the students as adult English learners. Furthermore, it is evident that the exposure has resulted in more language acquisition. The researchers also suggest further studies to explore the use of English songs of various genres to improve adult learners' vocabulary recognition.
