 **Aggregates play counts, filters duplicates, sorts your top tracks, and serves a clean, mobile-responsive HTML page via Nginx.**
 
 ## Features
-- 🕒 **All-Time Stats**: Aggregates total play counts and tracks the most recent timestamp for every song played.
-- 👥 **Multi-User Support**: Automatically detects all registered Navidrome users and creates individual cards for each.
-- 🧠 **Smart Sorting**: Ordered by total plays (descending), then last played date, then alphabetically by artist name.
-- 📱 **Fully Responsive**: Adapts cleanly to wide desktop screens and stacks vertically on mobile devices.
-- ⚡ **Zero Heavy Dependencies**: Runs entirely via standard Python libraries and a lightweight Nginx container.

 ## Setup & Instructions
 
 ### 1. Repository Structure
-Ensure you have your project directory set up with your two files:<br>
+Ensure you have your project directory set up with your files:
 
 your-dashboard-folder/<br>
 ├── dashboard.py<br>
-└── docker-compose.yml
+├── listener.py<br>
+├── docker-compose.yml<br>
+└── public/<br>          
 
-And make sure you have an empty public directory for the generated HTML output:
-`mkdir -p public`
+Create the public directory if it doesn't exist:
+```bash
+mkdir -p public
+```
 
 ### 2. Generate the Dashboard HTML
 You can run the Python script on-demand using a temporary Python container. 
 
-Mount your project folder to /app and your Navidrome data directory to /nddata:<br>
+Mount your project folder to `/app` and your Navidrome data directory to `/nddata`:
 
-`docker run --rm -v $(pwd):/app -v /path/to/your/navidrome/data:/nddata -e NAVIDROME_DB_PATH="/nddata/navidrome.db" -e OUTPUT_HTML_PATH="/app/public/index.html" python:3.11-slim python /app/dashboard.py`
+```bash
+docker run --rm -v $(pwd):/app -v /path/to/your/navidrome/data:/nddata python:3.11-slim python /app/dashboard.py
+```
 
 ### 3. Start the Web Server
 Spin up the Nginx container using Docker Compose:
-`docker compose up -d`
+```bash
+docker compose up -d
+```
 
 You can now view your dashboard in your browser at `http://<your-server-ip>:8081`.
 
-### Automation (Crontab)
-To keep the dashboard updated automatically, you can add a cron job on your host machine to regenerate the HTML page once a day at midnight.
+## Background Services & Automation
+
+### 1. HTTP Listener (Systemd Service)
+To power the "Regenerate Stats" button directly from the dashboard web UI, `listener.py` runs a lightweight HTTP server on port `8083` that triggers the update command when called.
+
+You can set this up as a persistent systemd service so it starts automatically on boot:
+
+1. Create the systemd service file:
+   ```bash
+   sudo nano /etc/systemd/system/dashboard-listener.service
+   ```
+
+2. Add the following configuration (make sure to replace `/home/username/dashboard` and `User=username` with your actual system path and username):
+   ```ini
+   [Unit]
+   Description=Dashboard Refresh Listener
+   After=network.target docker.service
+
+   [Service]
+   User=username
+   WorkingDirectory=/home/username/dashboard
+   ExecStart=/usr/bin/python3 /home/username/dashboard/listener.py
+   Restart=always
+
+   [Install]
+   WantedBy=multi-user.target
+   ```
+
+3. Enable and start the service:
+   ```bash
+   sudo systemctl daemon-reload
+   sudo systemctl enable dashboard-listener
+   sudo systemctl start dashboard-listener
+   ```
+
+### 2. Daily Cron Job (Optional)
+To keep the dashboard updated automatically once a day at midnight, you can add a cron job on your host machine.
 
 Open your crontab editor:
-`crontab -e`
+```bash
+crontab -e
+```
 
-Add the following line (making sure to replace `/home/username/dashboard` with your absolute project path and `/path/to/your/navidrome/data` with your actual Navidrome data path):
+Add the following line (making sure to replace paths with your absolute project path and actual Navidrome data path):
 
-`0 0 * * * docker run --rm -v /home/username/dashboard:/app -v /path/to/your/navidrome/data:/nddata -e NAVIDROME_DB_PATH="/nddata/navidrome.db" -e OUTPUT_HTML_PATH="/app/public/index.html" python:3.11-slim python /app/dashboard.py`
+```bash
