+- **Windows 10/11**
+- **Python 3.7+**
+- **yt-dlp.exe** (in `downloader/`)
+- **mutagen** (for ID3 tagging, optional)
 
 ## 🚀 Quick Start
 
-### 1. Download a Single Playlist
-
+### Download a Channel
 ```bash
-python download_karaoke.py https://www.youtube.com/playlist?list=YOUR_PLAYLIST_ID
+python download_karaoke.py https://www.youtube.com/@SingKingKaraoke/videos
 ```
 
-### 2. Download Multiple Playlists
-
-Create a `playlists.txt` file with your playlist URLs (one per line):
-
-```txt
-https://www.youtube.com/playlist?list=PLAYLIST1_ID
-https://www.youtube.com/playlist?list=PLAYLIST2_ID
-https://www.youtube.com/playlist?list=PLAYLIST3_ID
-```
-
-Then run:
-
+### Download from a List of Channels
 ```bash
-python download_karaoke.py --file playlists.txt
+python download_karaoke.py --file channels.txt
 ```
 
-## 📁 Project Structure
+### Download Only Songlist Songs
+```bash
+python download_karaoke.py --songlist-only
+```
 
+### Prioritize Songlist in Download Queue
+```bash
+python download_karaoke.py --songlist-priority
+```
+
+### Show Songlist Download Progress
+```bash
+python download_karaoke.py --songlist-status
+```
+
+### Limit Number of Downloads
+```bash
+python download_karaoke.py --limit 5
+```
+
+### Override Resolution
+```bash
+python download_karaoke.py --resolution 1080p
+```
+
+## 🧠 Songlist Integration
+- Place your prioritized song list in `docs/songList.json` (see example format below).
+- The tool will match and prioritize these songs across all available channel videos.
+- Use `--songlist-only` to download only these songs, or `--songlist-priority` to prioritize them in the queue.
+- Download progress for the songlist is tracked globally in `songlist_tracking.json`.
+
+#### Example `docs/songList.json`
+```json
+[
+  { "artist": "Taylor Swift", "title": "Cruel Summer" },
+  { "artist": "Billie Eilish", "title": "Happier Than Ever" }
+]
+```
+
+## 🛠️ Tracking & Caching
+- **karaoke_tracking.json**: Tracks all downloads, statuses, and formats
+- **songlist_tracking.json**: Tracks global songlist download progress
+- **channel_cache.json**: Caches channel video lists for performance
