Abstract
This study proposes an automatic playlist generation method that broadens interest in music and puts listeners in a positive mood. Our previous approach put listeners in a positive mood by listening to a playlist that gradually changes the song’s impression from “Low” to “High.” This study adds a new function to our previous study and broadens listener’s interest in the specific song in a playlist by emphasizing it. Specifically, the proposed method created two points in the playlist to arouse the notice of the specific song and shift listeners into positive moods in the playlist. The rapid song impression-changing point engages a listener’s interest in the song, and the gradual song impression-changing one puts listeners in a positive mood. This study conducted a subjective evaluation of the previous and proposed playlists. There were no significant differences between both methods in shifting listeners into positive moods. However, there were significant differences in attention to the emphasized and other songs. These results indicate that the proposed method may potentially expand interest in music and put listeners in a positive mood.
