Anyone who didn't play Rayman 2 as a child has no childhood or possibly even a soul. It is the definition of emotions with few words. Rayman as a series in its beginning is the idea of a painting come to life. Excuse me while I gather like six of my favorite Rayman songs that I can remember. If you haven't, play this game NOW. Find some medium of playing it. I don't care what. Rayman 2 is a great platformer and is probably the definition of innocent fun. You don't really think in Rayman, you just kinda feel, from what I recall of my early childhood. It may feel repetitive at times if you look at it, but Rayman 2 has otherwise aged really well as a game. Not as a cinematic piece, mind you, but it's a damn good game. Call it nostalgia goggles, I don't care. Try it.
As someone who also grew up with Rayman 2, I can attest to this. Or at least, the advice onto playing this game. I wouldn't say everything said above about the game, but it's still a great game.
But for shame, you included Band Land and Candy Chateau (which are great tracks, I'll admit it), yet you forgot about
Picture City? It's a shame that Rayman 1 was very difficult, so many people never really got far enough to hear this track. However, if you played Rayman 1 and managed to venture this far into the game, you were met with a beautiful piece of music. R?mi Gazel was a great composer for this game.
And in Rayman 2, I'll have to recommend
Spider Attack. This track sets an unsettling tone, and it freaked us out when we were kids. The spider was one of the most fearsome enemies due to it's speed, and whenever you heard this music, you knew you were in trouble. I'll never forget the first time I was playing this game and ran into one of those spiders.
And because I shouldn't just fill a post up with only Rayman, let's also throw in a track that many never got to hear.
Battletoads - Rat Race, the infamous game for it's notorious difficulty (I've come oh so close to clearing it, but The Revolution always gets me, which is odd, considering it's one of the easier stages). If there's one thing that Battletoads had other than it's difficulty however, it was it's soundtrack. It's simplistic, yet very catchy. Once again though, it's a shame people haven't really heard this track ingame, due to the previous challenges (personally, Terra Tubes gets me, Turbo Tunnel seems to be the most brought up stage though). Also, the same effect that you feel in the game is not present here, as when you progress further in the stage, the music speeds up, getting more and more frantic, and the races get more difficult. By itself, the track is nothing special. But if you've ever made it to Rat Race, you know what I mean when I state that it gets very frantic.
