Create a dynamic and visually engaging background image for a song. The scene features a vibrant cityscape at dusk with a colorful sunset casting a warm glow over the buildings. Musical elements like floating notes, abstract sound waves, and instruments such as guitars and keyboards are subtly integrated into the sky and city lights. The foreground includes a silhouette of a person with headphones, enjoying the music. The overall mood should be lively and uplifting, with rich, saturated colors and a sense of movement that reflects the rhythm and energy of the song. Add a subtle bokeh effect to enhance the atmosphere and make the image feel immersive and enchanting.
