Comparison
These are the results of the analysis of the data obtained with the Spotify API:
Most Streamed Songs per Year
More than half of the most played songs (60%) are from 2017, 2018 and 2019. And the top ten artists are Ed Sheeran (x2), Luis Fonsi, The Weeknd, Tones and I, Post Malone, Lewis Capaldi, Lil Nas X, Billie Eilish y The Chainsmokers.
Danceability Distribution
Danceability describes how suitable a track is for dancing based on a combination of musical elements including tempo, rhythm stability, beat strength, and overall regularity. A value of 0.0 is least danceable and 1.0 is most danceable. The median for the most played songs is 0,69, so we tend to like dancing songs the most.
Valence Distribution
Valence is a measure from 0.0 to 1.0 describing the musical positiveness conveyed by a track. Tracks with high valence sound more positive (e.g. happy, cheerful, euphoric), while tracks with low valence sound more negative (e.g. sad, depressed, angry). The median for the most played songs is 0,45, i.e. we are in the middle but we have a tendency towards sad songs.
Correlation between Valence and Danceability
So, we like dance songs but we also like sad songs? They don't correlate with each other? Well, I calculated the correlation between valence and danceability and there is a positive correlation but it is moderate (0,52). Also there is a noticeable group of songs that have high danceability but low valence.
