## 🔧 Technical Changes Summary

### Frontend (`backend/templates/index.html`)
```javascript
// FIXED: Uninitialized variable error (Line 3248)
function loadLibraryData() {
    const libraryContent = document.getElementById('libraryContent');
    // Removed duplicate: const libraryCount = document.getElementById('libraryCount');
    // ... existing code ...
    const libraryCount = document.getElementById('libraryCount'); // Local scope
    libraryCount.textContent = `${data.total} songs`;
}
```

### Backend (`backend/services/jellyfin_service.py`)
```python
# ENHANCED: Artist data processing with robust error handling
def process_track_data(track):
    artist = track.get('Artists', [{}])
    if isinstance(artist, list) and len(artist) > 0:
        artist_name = artist[0].get('Name', 'Unknown Artist') if isinstance(artist[0], dict) else str(artist[0])
    else:
        artist_name = str(artist) if artist else 'Unknown Artist'
    return artist_name
```

### Download Service (`backend/services/download_service.py`)
```python
# IMPROVED: Output template and progress parsing
output_template = '/data/{artist}/{album}/{title}.{output-ext}'
# Enhanced stage detection for better progress reporting
```
