Modeling the state of mind when listening to Positive Mood Playlist using Bayesian inference

Abstract

In this study, we modeled and evaluated the state of mind when a person listens to a playlist that makes them feel mood positive. We compared models of four different playlists and found that listening to a Positive Mood Playlist changed a personal state of mind. This is consistent with the results of a previous study, which showed that playlists with gradually changing song activation levels positively affect personal moods. These results suggest that the model proposed in this study may be able to reproduce a personal state of mind.
