A clean, professional minimalist circular 3D logo icon for a children's music channel, isolated on a solid dark background with no external decorative elements or doodles around the circle. In the very center, a cute and happy cartoon disco ball planet character with big expressive eyes and a wide cheerful smile. The facial features smoothly and seamlessly blend into the disco ball structure, with no sharp borders or outlines, appearing as if the face naturally emerges from the mosaic grid. The disco ball features smooth, glossy tiles in a specific color palette: deep hot pink (#ff0054), vibrant grass green (#45842a), and soft pastel pink (#faa0a2). The character is wearing large, colorful 3D headphones that perfectly wrap around it, matching these exact colors. Professional studio lighting with bright, clean reflections, smooth textures, modern Pixar and claymation style, strict minimalist composition with zero small cluttered details, high contrast, perfect for a mobile app icon.
