Create a vibrant digital illustration for a T-shirt design that embodies the essence of pop culture through sports and music. The design should feature bold symbols such as a guitar crossed with a soccer ball, surrounded by dynamic elements like musical notes and sports equipment. Use a bright color palette with electric blues, fiery reds, and sunny yellows to create an energetic atmosphere. The background should be minimalist, allowing the symbols to stand out prominently. The composition should be balanced, with the guitar and soccer ball at the center, drawing the viewer's eye. Consider adding a catchy phrase like "Rock Your Game" in a playful, modern font at the bottom, ensuring it complements the overall design without overpowering the symbols.
