# 🎵 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)

```bash
pip install requests ytmusicapi rich
```

> **Note:** if you hit `ModuleNotFoundError: No module named 'idna'` from
> `requests`, repair it with:
> ```bash
> 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).

```bash
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.      |

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

---

## 🧑‍💻 Usage

```bash
./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

```bash
# 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

```text
<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`).

PRs welcome. This script is middleware around Lidarr + yt-dlp, not a Lidarr
replacement. Keep it a single bash-friendly executable.
