This Sega Tunes CD "Virtual Sonic" claims that it has "Enhanced music inspired by the worlds of Sonic". However, it seems to be drawing from mostly Sonic & Knuckles with a bit of Spinball, much like the "Sonic & Knuckles" one above.
The cover is somewhat garish with the red Sega Tunes strip over the bright green and saturated blue of Sonic. You can see this is one of their early attempts at making him 3D...although his pupil is actually some sort of raised pebble on his eye (!)
