Spotify determines what songs to play next for listeners based on a couple of key properties of that song, such as danceability, acoustics, and energy amongst others. Each year, the Spotify Top 100 consists of the most popular songs for that year. Note that this does not necessarily mean that the song was released that year, it indicates that it was one of the most played. Below, I analyzed the relationship between different genres, artists, and songs.
To examine the raw data, feel free to search in the database below.
Spotify song properties often have high correlations between different ones. For instance, as danceability increases, there is an increase in energy. However, some songs are outliers. For example, Mr. Brightside by The Killers has a danceability of 35 with an energy of 95.
Contemporary R&B as a genre shows the highest median level of acoustics along with Canadian Pop. Again, this may be due to the popularity of Beiber on the top 100.
