Design a T-shirt graphic that celebrates the fusion of sports and music in pop culture. The digital illustration should feature iconic symbols such as a basketball intertwined with a microphone, radiating vibrant colors like neon green and hot pink. Surround the central imagery with abstract shapes and patterns that evoke movement and rhythm, reflecting the energy of both sports and music. The background should be kept simple to enhance the focus on the main elements. Incorporate a bold, stylized text that reads "Play Hard, Jam Harder" in a graffiti-inspired font, positioned above the symbols to create a cohesive and engaging design.
