🎵 MusicFetch

MusicFetch is a smart command-line utility that finds music by searching Lidarr (your music collection manager) and YouTube Music at the same time, shows you the top hits in an interactive picker, and downloads/queues whatever you choose. It accepts:

• A free-form query: an artist, an album, a track title, or combos like "Artist - Title" or "Artist - Album" (e.g. "ODESZA - Bloom", "Daft Punk", "Discovery").
• A URL (e.g. "https://music.youtube.com/watch?v=..." or a regular YouTube URL).

Lidarr is tried first by default. If you pick a Lidarr album but no indexer release is available, MusicFetch automatically falls through to the top YouTube hit. YouTube downloads prefer YouTube Music URLs so album art and tags are correct.

🚀 Features

• One unified picker showing the top hits from Lidarr and YouTube together, with matching keywords bolded.
• Lidarr-first flow: pick an album → adds artist+album (monitored) → interactive indexer search → falls through to YouTube only if no release is found.
• Accurate YouTube metadata via ytmusicapi (real artist / album / year / album art), with yt-dlp scraping as a fallback.
• Explicit tag overrides on download so files are tagged from the chosen hit, not from scraped titles.
• Non-interactive, YouTube-first, dry-run, quality, limit, and source-restriction flags.

📦 Dependencies & Installation

🐍 Python

• Python 3.10+
• requests
• ytmusicapi (recommended — accurate YouTube Music metadata)
• rich (recommended — nicer picker table + bold keyword matching)

pip install requests ytmusicapi rich

Note: if you hit ModuleNotFoundError: No module named 'idna' from requests, repair it with:

pip install --force-reinstall idna requests

ytmusicapi and rich are optional — without them MusicFetch falls back to yt-dlp search scraping and a plain ANSI picker.

📼 External Tools

• yt-dlp (audio download/extraction) and ffmpeg (for -x extraction / embedding).

pip install -U yt-dlp
sudo apt install ffmpeg      # or your distro's equivalent

⚙️ Configuration

Set via environment variables:

Variable	Default	Purpose
LIDARR_API_KEY	(required for Lidarr)	Lidarr API key.
LIDARR_URL	http://localhost:8686	Lidarr base URL.
MUSICFETCH_ROOT	/media/music	Default output root folder.

export LIDARR_API_KEY="your-lidarr-api-key"

🧑‍💻 Usage

./musicfetch [OPTIONS] QUERY...

Options

Flag	Description
-n, --noninteractive	Auto-pick the top hit (no prompt).
-s, --ytsearch	Search/select YouTube first instead of Lidarr first.
-d, --dry-run	Show every action without executing it.
-q, --quality {best,320,m4a,opus,flac}	Audio quality/format (default best).
--limit N	Hits per source (default 10).
--lidarr-only	Skip YouTube.
--yt-only	Skip Lidarr.
-o, --root PATH	Output root folder (default /media/music).
--search-all	Search all albums when adding an artist to Lidarr.
--debug	Verbose output.

Examples

# Interactive: combined Lidarr + YouTube picker
./musicfetch "ODESZA - Bloom"

# Just an artist / just an album / just a title all work
./musicfetch "Daft Punk"
./musicfetch "Discovery"

# YouTube first, auto-pick top hit
./musicfetch -s -n "Daft Punk - Harder Better Faster Stronger"

# Dry run — see what would happen, change nothing
./musicfetch -d "ODESZA - Bloom"

# YouTube only, lossless preferred
./musicfetch --yt-only -q flac "Bonobo - Kerala"

# Download by URL (YouTube Music URL preferred for correct art)
./musicfetch "https://music.youtube.com/watch?v=xxxxxxxxxxx"

📁 Output Structure

<root>/
├── Artist Name/
│   ├── Album Name/   (managed by Lidarr)
│   └── youtube/      (yt-dlp downloads / fallbacks)

---

❓ Troubleshooting

• No Lidarr hits / "LIDARR_API_KEY not set": export your key and confirm LIDARR_URL is reachable.
• Wrong album art from YouTube: install ytmusicapi so MusicFetch can resolve proper YouTube Music URLs and metadata.
• yt-dlp errors: update with yt-dlp -U; ensure ffmpeg is installed for extraction/embedding.
• idna import error: pip install --force-reinstall idna requests.
• Permission denied writing files: ensure the output root exists and is writable (-o/--root or MUSICFETCH_ROOT).

🌐 REST API (Docker)

Run MusicFetch as an authenticated HTTP service inside your Lidarr Docker stack. A client POSTs a query; the server grabs the top hit non-interactively and runs the download as a background job you can poll. Every response includes a human-readable message (handy for Siri).

Configure & run

Set the network name in server/docker-compose.yml to your existing Lidarr stack network, then:

export LIDARR_API_KEY="your-lidarr-key"
export MUSICFETCH_API_KEY="a-long-random-secret"
docker compose -f server/docker-compose.yml up -d --build

Env var	Default	Purpose
MUSICFETCH_API_KEY	(required)	Shared secret clients send as X-API-Key.
MUSICFETCH_PORT	6769	Listen port.
LIDARR_URL	http://lidarr:8686	Lidarr base URL (stack network).
LIDARR_API_KEY	(required for Lidarr)	Lidarr API key.
MUSICFETCH_ROOT	/media/music	Music output root (bind-mounted).

TLS is expected to be handled by your upstream reverse proxy; the container serves plain HTTP on 6769.

Endpoints

Method	Path	Auth	Purpose
GET	/health	no	Liveness check.
POST	/fetch?q=...	yes	Grab top hit; returns a job_id.
GET	/jobs/{id}	yes	Poll job status.

POST /fetch params: q (required), quality (best,320,m4a,opus,flac), source (auto,lidarr,youtube).

curl examples

# Kick off a fetch
curl -X POST 'https://mf.izebra.net/fetch?q=Under%20My%20Skin' \
  -H 'X-API-Key: a-long-random-secret'
# -> {"message":"Found 'Under My Skin' ... Downloading now.","job_id":"a1b2c3","status":"queued","hit":{...}}

# Poll the job
curl 'https://mf.izebra.net/jobs/a1b2c3' -H 'X-API-Key: a-long-random-secret'
# -> {"message":"Finished downloading ...","status":"done","result":{...}}

🗣️ Siri Shortcuts integration

Make a shortcut that fetches music by voice ("Hey Siri, fetch music").

1. Shortcuts app → New Shortcut.
2. Add Ask for Input → Input Type Text, prompt "What should I fetch?". (Or use Dictate Text for fully spoken input.)
3. Add Text action, set it to: https://mf.izebra.net/fetch?q= then insert the Provided Input variable at the end. (Shortcuts URL-encodes query variables automatically.)
4. Add Get Contents of URL:
   • URL: the Text variable from step 3.
   • Method: POST.
   • Headers: add one — key X-API-Key, value your MUSICFETCH_API_KEY.
   • Request Body: leave as is (the query is in the URL).
5. Add Get Dictionary Value → Get Value for message in Contents of URL.
6. Add Speak Text → the Dictionary Value. Siri reads back "Found '…' … Downloading now."
7. (Optional) To confirm completion: add Get Dictionary Value for job_id, Wait ~20 seconds, Get Contents of URL on https://mf.izebra.net/jobs/<job_id> (same X-API-Key header), then Get Dictionary Value message → Speak Text again.

Rename the shortcut (e.g. "Fetch Music") — that phrase becomes the Siri trigger.
