Notes:

On Windows you might want to enable UTF-8 support throughout the system. This way windows can support special characters within song paths. You can enable this by doing this:

1. Windows btn + R -> intl.cpl
2. Hit the 2nd tab called "administritive"
3. Hit the button "Change System Locale..."
4. Tick the checkbox "Beta: Use Unicode UTF-8 for worldwide language support"
5. Restart pc

Also for Windows users if you want to allow "All Connections" for the webserver you need to run the application with Administrator privileges.
