Rspotify: Access to Spotify API via R

This package allows you to connect R to Spotify’s API and get information about Songs, Albums, Artists and Users.
This is an experimental package built up with functions that I’ve created to attend my specific needs (meaning I wasn’t really concerned with errors different than ones I got when it was written). Please, use it with caution.
So far I haven’t uploaded a stable version to CRAN but you can download from GitHub using devtools, type:
library(devtools)
install_github("tiagomendesdantas/Rspotify")
In order to access many of the functions you need an authenticated token. You can get one accessing this link to create a Spotify app and get app_id, client_id and client_secret. (Don’t forget to put http://localhost:1410/ in Redirect URIs)
keys <- spotifyOAuth("app_id","client_id","client_secret")
To get information about a specific user:
user <- getUser("t.mendesdantas",token=keys)
user$display_name # user name
# [1] "Tiago Dantas"
user$id
# [1] "t.mendesdantas" #user id
user$followers
# [1] 46
To search for an artist:
searchArtist("Regina+spektor")
# id name popularity genres type followers
# 3z6Gk257P9jNcZbBXJNX5i Regina Spektor 67 anti-folk artist 613837
To get information from an artist using the artist id:
regina<-getArtist("3z6Gk257P9jNcZbBXJNX5i")
To get information the albums available at spotify from a specific artist:
regina.albums<-getAlbums("3z6Gk257P9jNcZbBXJNX5i")
regina.albums$name #name of the albums
# [1] "Kubo and the Two Strings"
# [2] "What We Saw From The Cheap Seats"
# [3] "What We Saw From The Cheap Seats (Deluxe Version)"
# [4] "Live In London"
# [5] "Far"
# [6] "Far (Deluxe DMD)"
# [7] "Begin To Hope"
# [8] "Begin To Hope (Special Edition)"
# [9] "Begin To Hope (U.S. Version)"
# [10] "Soviet Kitsch (U.S. Version)"
To get the songs from a specific album:
# getting the songs from the album "what we saw from the cheap seats"
#from Regina Spektor
regina.whatwesaw<-getAlbum("3Etyu2JmgiQTQztLz6RxDX") #"3Etyu2JmgiQTQztLz6RxDX" is theid for the album.
To get the features from a specific song:
# getting the song features from "Don't Leave Me [Ne Me Quitte Pas]" 
#from the album "what we saw from the cheap seats" from Regina Spektor
song<-getFeatures("0y5HWbAnJ6qrjeBuFL52hO",token=keys) #"0y5HWbAnJ6qrjeBuFL52hO" is the id for the album.
To get the playlists from a specific user:
wh.playlist <- getPlaylist("thewhitehouse",token=keys) #playlist from the White House
wh.playlist
#id name ownerid tracks
#1 6ujhXmg8SXjdkdCZ2TchTY The Bidens' 2016 Summer Playlist thewhitehouse 15

Nice examples

One nice idea is to create networks of related artists. Eg. This is a network of related artists from the top 100 artists at spotify (Basically all you need to do is use getPlaylistSongs and getRelated to get the data).

 

Another example is to use getFeatures to extract features and play with that. In this example I use getFeatures and getPlaylistSongs to extract song features from the “What we saw from the cheap seats” from Regina Spektor and the song features from the Top 20 songs at spotify (extracted in august 2016). I assume that Reginas’ songs are not very similar to the ones that make a lot of success…This is sad because her songs are awesome =( . Then I use Hierarchical cluster to see if Reginas’ songs would stay in a different cluster based on its features.

Apparently it does! 8 out 11 of her songs would be in the same cluster (cluster on the right). From the 3 “misclassified” 2 were singles (“Don’t Leave Me [Ne Me Quitte Pas]” and “All the Rowboats”). So it is not strange to see them in a cluster with the top 20 songs.
That’s it! Hope you find this useful!
