spotifyr

Overview

spotifyr is an R wrapper for pulling track audio features and other information from Spotify’s Web API in bulk. By automatically batching API requests, it allows you to enter an artist’s name and retrieve their entire discography in seconds, along with Spotify’s audio features and track/album popularity metrics. You can also pull song and playlist information for a given Spotify User (including yourself!).

Installation

CRAN version 2.1.0 (recommended)

install.packages('spotifyr')

Development version

devtools::install_github('charlie86/spotifyr')

Authentication

First, set up a Dev account with Spotify to access their Web API here. This will give you your Client ID and Client Secret. Once you have those, you can pull your access token into R with get_spotify_access_token().

The easiest way to authenticate is to set your credentials to the System Environment variables SPOTIFY_CLIENT_ID and SPOTIFY_CLIENT_SECRET. The default arguments to get_spotify_access_token() (and all other functions in this package) will refer to those. Alternatively, you can set them manually and make sure to explicitly refer to your access token in each subsequent function call.

Sys.setenv(SPOTIFY_CLIENT_ID = 'xxxxxxxxxxxxxxxxxxxxx')
Sys.setenv(SPOTIFY_CLIENT_SECRET = 'xxxxxxxxxxxxxxxxxxxxx')

access_token <- get_spotify_access_token()

Authorization code flow

For certain functions and applications, you’ll need to log in as a Spotify user. To do this, your Spotify Developer application needs to have a callback url. You can set this to whatever you want that will work with your application, but a good default option is http://localhost:1410/ (see image below). For more information on authorization, visit the offical Spotify Developer Guide.

What’s the most joyful Joy Division song?

My favorite audio feature has to be “valence,” a measure of musical positivity.

joy <- get_artist_audio_features('joy division')

joy %>% 
    arrange(-valence) %>% 
    select(track_name, valence) %>% 
    head(5) %>% 
    kable()

track_name	valence
Passover - 2020 Digital Master	0.946
Colony - 2020 Digital Master	0.829
Atrocity Exhibition - 2020 Digital Master	0.790
Isolation - 2020 Digital Master	0.778
A Means to an End - 2020 Digital Master	0.774

Now if only there was some way to plot joy…

Joyplot of the emotional rollercoasters that are Joy Division’s albums

library(ggplot2)
library(ggridges)

ggplot(
    joy, 
    aes(x = valence, y = album_name)
    ) + 
geom_density_ridges() + 
theme_ridges() +
labs(title = "Joyplot of Joy Division's joy distributions", 
     subtitle = "Based on valence pulled from Spotify's Web API with spotifyr")

Sentify: A Shiny app

This app, powered by spotifyr, allows you to visualize the energy and valence (musical positivity) of all of Spotify’s artists and playlists.
