ABSTRACT
With the increasing prevalence of mental health issues, music therapy has gained attention as a non-pharmacological intervention, and deep learning techniques have shown promise in music emotion recognition and preference prediction. This study constructed a deep neural network model (CNN+RNN/EEGNet) to efficiently identify music type preferences and examine the influence of user familiarity on prediction accuracy. EEG signals were collected using a four-channel Muse S wearable device, and user familiarity scores were used as input features. The study followed a four-stage workflow: preparation, experimental design, model construction, and result analysis. In the experimental design, music was categorized into rock, ballad, and folk, and EEG data and familiarity ratings were collected for each category. Data was trained and tested using CNN+RNN or EEGNet models, and model performance was evaluated via subject-level 10-fold cross-validation. Results indicated that predicting all music types with EEG data alone achieved an accuracy of 82.28 ± 3.42%. For individual music types, accuracies were 91.13 ± 3.60% (rock), 91.83 ± 2.07% (ballad), and 87.87 ± 4.76% (folk). When incorporating user familiarity as a feature and using a multi-level rating output, overall prediction accuracy increased to 94.94 ± 1.61%, while individual music type accuracies reached 99.15 ± 1.56% (rock), 98.51 ± 2.30% (ballad), and 98.21 ± 2.60% (folk). These results demonstrate that combining familiarity features with a multi-level scoring system significantly improves the prediction of music preferences. By using an affordable, wearable Muse S EEG device and leveraging user familiarity, this study successfully developed a highly effective deep neural network model (CNN+RNN/EEGNet) for recognizing music type preferences. The findings indicate that both overall and individual music-type predictions benefit from the inclusion of familiarity information, highlighting the potential of this approach for personalized music recommendations and music therapy applications.
