Mostrar el diálogo con la portada actual del álbum de iTunes

Sí, lo es. Esto es lo que se me ocurrió. Es tarde, así que me temo que es un poco duro...

1. descargar Pashua - una herramienta gratuita para crear cuadros de diálogo personalizados
2. copiar la aplicación y Pashua.scpt a la carpeta de aplicaciones
3. Pegue el siguiente código y ajústelo a su gusto.
