Music Mood Classification Using Intro and Refrain Parts of Lyrics

In this paper, we propose an lyrics-based classification approach. It estimates a mood of a song with only intro and refrain parts of lyrics. In general, the intro part creates a specific atmosphere of a song, and the chorus part is the strongest part of the song. The proposed method detects important features significantly associated with the mood of songs from the both parts. By calculating the similarity between terms of the parts and eight basic emotions, it can classify songs according to mood.
