I love the Sega CD start-up. The Sega logo, Sonic flicks stars at it, then a low-key "saaaayyy-gaaaaahhhh" tune. Then the REAL music begins. The Sega CD logos spoins and twirls over a space scene while an incredible theme song plays. First time I saw it, it was just magical to me. Sometime I turn my Sega CD on without a game, just so I can see and hear that start-up sequence.
