SURVIVAL ANALYSIS OF THE BRAZILIAN SPOTIFY RANKING: DIFFERENCES BETWEEN NATIONAL AND INTERNATIONAL ARTISTS

This article used public data provided by the streaming company Spotify with the objective of analyzing the permanence of artists in the Brazilian ranking throughout the year of 2017. A total of 1084 songs were accessed using the spotifycharts package, which allows the extraction of the daily Top 200 songs of any of the 53 countries that Spotify streaming services are present. For manipulation, treatment and analysis of the data, the packages lubridate (GROLEMUND, 2011), dplyr (WICKHAM; FRANCOIS, 2015), forcats (WICKHAM, 2017) and ggplot2 (WICKHAM, 2016) were used. The results show a greater proportion of national artists in all months of the year 2017. Given that an artist can have more than one song at the same time, the analysis shows artists with more than 20 songs among the most listened. On top of that, International songs' survival curve decreases faster than the national's survival curve on both Top 200 and Top 10 rankings. Finally, the use of the survival analysis technique to interpret the permanence of songs in the ranking of the most heard is discussed.
