# Apple Music Integration

Guide for integrating with Apple Music. Covers AppleScript (macOS), MusicKit API (cross-platform), and the critical library-first requirement.

## When to Use

Invoke when users ask to:
- Manage playlists (create, add/remove tracks, list)
- Control playback (play, pause, skip, volume)
- Search catalog or library
- Add songs to library
- Access listening history or recommendations

## Critical Rule: Library-First Workflow

**You CANNOT add catalog songs directly to playlists.**

Songs must be in the user's library first:
- ❌ Catalog ID → Playlist (fails)
- ✅ Catalog ID → Library → Playlist (works)

**Why:** Playlists use library IDs (`i.abc123`), not catalog IDs (`1234567890`).

This applies to both AppleScript and API approaches.

## Platform Comparison

| Feature | AppleScript (macOS) | MusicKit API |
|---------|:-------------------:|:------------:|
| Setup required | None | Dev account + tokens |
| Playlist management | Full | API-created only |
| Playback control | Full | None |
| Catalog search | No | Yes |
| Library access | Instant | With tokens |
| Cross-platform | No | Yes |

---

# AppleScript (macOS)

Zero setup. Works immediately with the Music app.

**Run via Bash:**
```bash
osascript -e 'tell application "Music" to playpause'
osascript -e 'tell application "Music" to return name of current track'
```

**Multi-line scripts:**
```bash
osascript <<'EOF'
tell application "Music"
    set t to current track
    return {name of t, artist of t}
end tell
EOF
```

## Available Operations

| Category | Operations |
|----------|------------|
| **Playback** | play, pause, stop, resume, next track, previous track, fast forward, rewind |
| **Player State** | player position, player state, sound volume, mute, shuffle enabled/mode, song repeat |
| **Current Track** | name, artist, album, duration, time, rating, loved, disliked, genre, year, track number |
| **Library** | search, list tracks, get track properties, set ratings |
| **Playlists** | list, create, delete, rename, add tracks, remove tracks, get tracks |
| **AirPlay** | list devices, select device, current device |

## String Escaping

Always escape user input:
```python
def escape_applescript(s):
    return s.replace('\\', '\\\\').replace('"', '\\"')

safe_name = escape_applescript(user_input)
script = f'tell application "Music" to play user playlist "{s
