|
Returns only the artist names for the tracks in a given Spotify playlist
|
|
|
|
Playlist argument can be a playlist name or a playlist ID (get this from spotify_playlists.sh)
|
|
|
|
\$SPOTIFY_PLAYLIST can be used from environment if no first argument is given
|
|
|
|
|
|
Outputs 1 artist per line, so tracks with multiple artists become multiple artist lines
|
|
|
|
This is useful for piping to 'sort | uniq -c' to:
|
|
|
|
1. Find top artists per playlist by counting the number of tracks per artist
|
|
2. Find top blacklisted artists by doing the above for my Blacklist playlist (done the Spotify-Playlists repo)
|
|
|
|
Example:
|
|
|
|
SPOTIFY_PRIVATE=1 spotify_playlist_artists.sh Blacklist | sort | uniq -c | sort -k1nr
