Rainbow Road is the only course in the game to get completely unique music, and it really helps to set the stage for the game's grand finale: a multicoloured track IN SPACE! It may be a 16-bit composition that sounds rather blocky nowadays, but it still remains firmly Vindicated by History.Of course, for other people, this theme takes on a different meaning entirely.
Vanilla Lake 's theme embodies the jolly feel of a snow level.Both Koopa Beach courses in this game kicked off the franchise's longstanding reputation for making great beach stages and great music to accompany them. The music for Koopa Beach has a very relaxing tropical island vibe to it.It makes the track sound truly threatening as you race through the course. Bowser Castle 's music is also derived from Super Mario World, being a remix of Bowser's intro and boss theme from that game.Its music, an even creepier remix of the Ghost House theme from Super Mario World, goes a long way towards setting the mood. Mario Kart courses are generally cheery and lighthearted, but even as early as the first game, Ghost Valley demonstrates that that's not always the case.
It even got remixed for Super Smash Bros.
