Everyone call me elf monster.
I liked the cave ones, specifically the two that play in Crystal Palace. The first stage to Mr. Dark's Dare was also pretty awesome...and Mr. Stone's battle theme. The 'pencil scratching' theme was also pretty good, and so was the third stage to Bongo Hills. Overall, it's one of those better soundtracks, though it's a little childish (which is paradoxical, given the frustrating difficulty of the game D:)
Yeah, I know. Even my mum (who was an avid rayman fan) struggled on most of the levels. XD
I used to be scared of the swamps of forgetfulness level. The music made me cry.
