Download Spotify tracks as Ogg Vorbis with a premium account.
This library uses librespot.
The code is kind of ugly, it has been written by Ferris newbies only 😁
To download tracks as "artists" - "title".ogg, run:
oggify "spotify-user" "spotify-password" urls_list
Oggify reads from stdin and looks for a track/album/playlist URL or URI on each line. The two formats are those you get with the track menu items "Share->Copy Song Link" or "Share->Copy Song URI" in the Spotify client, for example open.spotify.com/track/1xPQDRSXDN5QJWm7qHg5Ku or spotify:track:1xPQDRSXDN5QJWm7qHg5Ku.
If you need MP3s instead of Oggs files, this piece of shell script can help you:
for ogg in *.ogg; do
ffmpeg -i "$ogg" -map_metadata 0:s:0 -id3v2_version 3 -codec:a libmp3lame -qscale:a 2 "$(basename "$ogg" .ogg).mp3"
done
