Listen to songs in unfamiliar genres (26) Among the 11 properties, statistical differences between two playlist
types were observed for nine properties
 People tend to emphasize different properties when creatinga chorus-playlist compared to creating a usual playlist
 Although most methods for recommending songs to playlists focus on
the song order, it is less important in creating chorus-playlists
 In usual playlists, the diversities of artists and genres tend to be low.
However, to support users creating chorus-playlists, it is important torecommend songs to diversify artists, genres, and moods
