oggify

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

This program uses librespot,
and as such, requires a Spotify Premium account to use.
It supports downloading single tracks and episodes, but also entire playlists, albums and shows.

Usage

To download a number of links as <artist(s)> - <title>.ogg, run

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

Oggify reads from standard input and looks for a URL or URI in each line,
and checks whether it is a valid Spotify media link. If it is not valid, it will be ignored.

The two formats are those you get with the menu items
"Share → Copy Link" or "Share → Copy URI" in the Spotify client,
for example
open.spotify.com/track/1xPQDRSXDN5QJWm7qHg5Ku
or
spotify:track:1xPQDRSXDN5QJWm7qHg5Ku.

Once you close the standard input or write "done" into it,
it will start downloading all tracks and episodes in order of input
into your current working directory.

Helper script

A second form of invocation of oggify is

oggify "spotify-premium-user" "spotify-premium-password" "helper_script" < link_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 (🤮)

Don't do that, please. You will just lose quality. If you want to do it anyway:

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
