So valence provides a measure of how sad a song sounds from a musical perspective. Another key component of a song’s sentiment is its lyrics, and it just so happens that Genius Lyrics also has an API to pull track-level data. To see how sadness evolved across all nine albums, I calculated the average gloom index per album and plotted each song by album release date.
