The intro cinematic of Sonic CD for the Sega CD. This is the US intro with the "Sonic Boom" theme song by Spencer Nilsen. (A lot of people argue that the Japanese version, "Toot Toot Sonic Warrior" is better, but they are wrong. :D)

I remember the first time I saw this, and how I thought it was the most awesome thing I'd ever seen in my life. Now that I look back, perhaps I was right . . .
