Music Downloader 🎶 🎧 💃 🦄

Features

• download songs, albums, public playlists from Deezer.com (account is required, free plan is enough)
• download Spotify playlists (by parsing the Spotify website and download the songs from Deezer)
• download as zip file (including m3u8 playlist file)
• 320 kbit/s mp3s with ID3-Tags and album cover (UPDATE: right now only 128bkit/s mp3 works, see #66)
• download songs via yt-dlp
• KISS front end
• MPD integration (use it on a Raspberry Pi!)
• simple REST api

How to use it

There is a settings file template called settings.ini.example. You can specify the download directory with download_dir. Pressing the download button only downloads the song/album/playlist. If you set use_mpd=True in the settings.ini the backend will connect to mpd (localhost:6600) and update the music database. Pressing the play button will download the music. If use_mpd=True is set the mpd database will be updated and the song/album/playlist will be added to the playlist. In settings.ini music_dir should be the music root location of mpd. The download_dir must be a subdirectory of music_dir.

As Deezer sometimes requires a captcha to login the auto login features was removed. Instead you have to manually insert a valid Deezer cookie to the settings.ini. The relevant cookie is the arl cookie.

Run it as a service

We use it with nginx and ympd as mpd frontend

• / goes to ympd
• /d/ goes to the downloader

The deployment directory contains a systemd unit file and a nginx vhost config file. There is also a patch to add a link to the ympd frontend. The debug tab will show you the debug output of the app.

Try it out

vagrant up
vagrant ssh
sudo vim /opt/deezer/app/settings.ini # insert your Deezer cookie
/opt/deezer/app/venv/bin/python /opt/deezer/app/app.py # start the backend

# On the host:
xdg-open http://localhost:5000 # view frontend in the browser
ncmpcpp -h 127.0.0.1 # try the mpd client

Docker

You can use the Docker image hosted on hub.docker.com. Login into your free Deezer account and grab the arl cookie. Then:

mkdir downloads
sudo docker run -p 5000:5000 --volume $(pwd)/downloads/:/mnt/deezer-downloader --env DEEZER_COOKIE_ARL=changeme kmille2/deezer-downloader:latest 
xdg-open http://localhost:5000

If you want to debug or build it from source: there is a docker-compose file in the docker directory. The docker/downloads directory is mounted into the container and will be used as download directory. You have to check the permissions of the docker/downloads directory as docker mounts it with the same owner/group/permissions as on the host. The deezer user in the docker container has uid 1000. If you also have the uid 1000 then there should be no problem. For debugging: sudo docker-compose build --force-rm && sudo docker-compose up
