CRAN_Status_Badge

Overview

spotifyr is a 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

Development version (recommended)

devtools::install_github('charlie86/spotifyr')

The development version now includes functions from the geniusR package from Josiah Parry.

CRAN version 1.0.0 (Note: this is somewhat outdated, as it takes extra time to submit and pass CRAN checks)

install.packages('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()

Usage

What was The Beatles’ favorite key?

library(spotifyr)
beatles <- get_artist_audio_features('the beatles')
library(tidyverse)
library(knitr)

beatles %>% 
    count(key_mode, sort = TRUE) %>% 
    head(5) %>% 
    kable()
key_mode n

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
These Days - Live 0.949
Passover - 2007 Remastered Version 0.941
Colony - 2007 Remastered Version 0.808
Atrocity Exhibition - 2007 Remastered Version 0.787
Incubation - Live 0.785

Now if only there was some way to plot joy…

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

Parallelization

get_artist_audio_features(), get_artist_albums(), get_album_tracks(), get_playlist_tracks(), and get_user_playlists() can run in parallel using the furrr package. To enable this feature, set parallelize = TRUE. You can also adjust the evaluation strategy by setting future_plan, which accepts a string matching one of the strategies implemented in future::plan() (defaults to "multiprocess").

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.

Dope stuff other people have done with spotifyr
