arr-scripts / Deezer Integration

Lidarr uses arr-scripts by RandomNinjaAtk to download music from Deezer via deemix. This is the primary download source since usenet indexers have zero coverage for non-English music (Italian, Japanese, etc.).

How it works

arr-scripts runs as s6 services inside the Lidarr container
The Audio service polls Lidarr's missing albums queue every cycle
For each missing album, it searches Deezer using fuzzy title matching (Damerau-Levenshtein distance)
On match, it calls deemix to download at 320kbps MP3 (Deezer Premium)
Files are placed in /config/extended/import/ and Lidarr is notified via API to import them

File locations on Atlantis

Path	Purpose
`/volume2/metadata/docker2/lidarr/extended.conf`	arr-scripts config — not in git (contains ARL token)
`/volume2/metadata/docker2/lidarr-scripts/custom-cont-init.d/scripts_init.bash`	Init script that runs on every container start
`/volume2/metadata/docker2/lidarr-scripts/custom-services.d/`	s6 service definitions (populated automatically on first start)

extended.conf key settings

enableAutoConfig="true"      # Required sentinel — all services check this first
enableAudio="true"           # Set to "false" to pause downloads
dlClientSource="deezer"
audioFormat="native"
audioBitrate="high"          # "high" = 320kbps MP3 with native format (NOT a number)
arlToken="..."               # Deezer session cookie — expires ~3 months, not in git
enableBeetsTagging="true"
beetsMatchPercentage="90"
enableReplaygainTags="true"

ARL token: Get from deezer.com → DevTools → Application → Cookies → arl. Requires Deezer Premium.

Pausing/resuming downloads

Quick (via Portainer console exec into lidarr):

s6-svc -d /run/service/custom-svc-Audio   # pause
s6-svc -u /run/service/custom-svc-Audio   # resume

Persistent (survives restarts): Edit /volume2/metadata/docker2/lidarr/extended.conf, set enableAudio="false", restart container.

scripts_init.bash — why it exists

setup.bash (downloaded from GitHub) silently fails to install several Python packages on Alpine due to setuptools build errors. scripts_init.bash re-installs them explicitly after setup.bash runs:

yq — Python yq whose xq binary replaces Alpine's xq (v1.x outputs XML passthrough instead of JSON)
pyxdameraulevenshtein — Damerau-Levenshtein distance for fuzzy album title matching
deemix — actual Deezer downloader
colorama, pylast, mutagen, langdetect, apprise, r128gain — supporting packages

Without these, downloads fail silently or the scripts get stuck in a "not ready" loop forever.

Compose volumes

volumes:
  - /volume2/metadata/docker2/lidarr:/config
  - /volume1/data:/data
  - /volume3/usenet:/sab
  - /volume2/metadata/docker2/lidarr-scripts/custom-services.d:/custom-services.d
  - /volume2/metadata/docker2/lidarr-scripts/custom-cont-init.d:/custom-cont-init.d

Indexers

Usenet indexers (NZBgeek, NzbPlanet, etc.) have near-zero coverage for non-English music. Deezer via arr-scripts is the primary source. Usenet indexers still handle English/mainstream releases when they appear.
