Design a graffiti-inspired T-shirt print featuring a grinning skull wearing oversized headphones. The skull should have bold black outlines for clear separation, with graffiti-style spray paint effects in vibrant blue and orange around it. Include dynamic elements like music notes and sound waves, each with strong borders. Render the design on a transparent background, ensuring it appeals to teenage boys who love edgy, music-themed graphics. Provide the artwork in a high-resolution vector format.
