oggify

Download Spotify tracks to Ogg Vorbis (with a premium account).

This library uses librespot. It is my first program in Rust so you may see some horrors in the way I handle tokio, futures and such.

Usage

To download a number of tracks as "artists" - "title".ogg, run

oggify "spotify-premium-user" "spotify-premium-password" < tracks_list

Oggify reads from stdin and looks for a track URL or URI in 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.

Helper script

A second form of invocation of oggify is

oggify "spotify-premium-user" "spotify-premium-password" "helper_script" < tracks_list

In this form helper_script is invoked for each new track:

helper_script "spotify_id" "title" "album" "artist1" ["artist2"...] < ogg_stream

The script tag_ogg in the source tree can be used to automatically add the track information (spotify ID, title, album, artists) as vorbis comments.

Converting to MP3

Use oggify with the tag_ogg helper script as described above, then convert with ffmpeg:

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
