The Data Science of “Someone Like You” or Sentiment Analysis of Adele’s Songs
An extensive analysis of Adele's songs using Natural Language Processing (NLP) on the lyrics, to uncover the underlying emotions and sentiments.
Songs associated with different emotions
So, specifically which song is positive? Which one is negative? And which songs are most associated with emotions such as joy, sadness, anger? Let’s find out!
The chart shows that ‘Why do you love me’ is the most positive song while ‘He won’t go’ and ‘River Lea’ are the negative songs. In terms of anger and sadness ‘River Lea’ and ‘Rolling in the deep’ score the highest respectively.
Relationship between the emotions and the albums
We will find out how her emotion has evolved from the release of the first album and dominance of certain emotions in the albums.
The following chord diagram shows that her latest album, i.e., 25 is the most joyful one. Also, the scores for ‘joy’ has increased with the release of new albums. In terms of sadness, ‘21’ scores the highest.
Measuring valence of her albums
This is one my favourite audio features -- essentially valence can be described as a measure of the musical positiveness conveyed by a track. Tracks with high valence sound more positive (happy, cheerful, euphoric), while tracks with low valence sound more negative (sad, depressed, angry). We’ll be using Spotify API to extract the data and plot.
Note that the Spotify API pulled results for 34 tracks whereas Genius API gave 41 tracks. So, we cannot really compare the results of this plot with previous plot
According to this plot album 25 is the least positive album with average value of 0.28 whereas the other two albums are close to each other with average valence score of 0.41.
