New spotifyr R Package Release
2.2.1: Thoroughly modernized exception handling, documentation, and some bug fixes
I have been a very long-time user of Charlie Thomson’s spotifyr R package, which is probably the most used open-source music analytics software in the world. It provides programmatic access to the Spotify Web API, which contains access to the former Echo Nest quantitative musicology engine.
It is an essential part of the Digital Music Observatory’s streaming analysis and our Listen Local apps designed for our trustworthy AI experiments and independent artist services. I am extremely proud to announce that after a very thorough modernization of the package’s exception handling, documentation, and code dependencies that I did in the last week, the package has passed again the peer-review standards and it is back on CRAN.
The package is an excellent starting to point for R newbies to try their hands on musicology analysis with a few keystrokes. And of course, it is an essential part of the research infrastructure of musicology worldwide in far more advanced applications.

library(dplyr) library(purrr) library(knitr) beatles %>% count(key_mode, sort: TRUE) %>% head(5) %>% kable()
Get your most recently played tracks
library(lubridate) get_my_recently_played(limit: 5) %>% mutate( artist.name: map_chr(track.artists, function(x) x$name), played_at: as_datetime(played_at) ) %>% select( all_of(c("track.name", "artist.name", "track.album.name", "played_at")) ) %>% kable()

Find Your All Time Favorite Artists
get_my_top_artists_or_tracks(type: 'artists', time_range: 'long_term', limit: 5) %>% select(.data$name, .data$genres) %>% rowwise %>% mutate(genres: paste(.data$genres, collapse: ', ')) %>% ungroup %>% kable()
|Japanese Breakfast||art pop, bubblegrunge, eugene indie, indie pop, indie rock, philly indie|
|Haley Bonar||melancholia, stomp and holler|
|Balthazar||belgian indie, belgian rock, dutch indie, dutch rock, ghent indie|
|Buildings Breeding||indie fuzzpop|
|Angus & Julia Stone||australian indie folk, indie folk, stomp and holler|
What could I say? I travelled Australia listening only to Angus & Julia Stone, the Buildings Breeding have been with me since I discovered them on my first iPod, in one of the first podcasts, the Indiefeed. I created my Kickstarter account back in 2010 to support Haley Bonar’s third album. And the year before I was very much into Japanese Breakfast and Balthazar.
Find your favorite tracks at the moment

Our Work with spotifyR
- Trustworthy AI: Check Where the Machine Learning Algorithm is Learning From
- Recommendation Systems: What can Go Wrong with the Algorithm?
- Feasibility Study On Promoting Slovak Music In Slovakia & Abroad
- Forgetify: Popular Music That Nobody Listens To
A key mission of our Digital Music Observatory, which is our modern, subjective approach on how the future European Music Observatory should look like, is to not only to provide high-quality data on the music economy, the diversity of music, and the audience of music, but also on metadata. The quality and availability, interoperability of metadata (information about how the data should be used) is key to build trustworthy AI systems. We rely on spotifyr to fulfil this mission.
