I'm disappointed to see that only one song was remixed out of this game. I'd like to request that the Waterfall track to Donkey Kong Country 3: Dixie's Double Trouble! be remixed.

Add to this, from Donkey Kong Country 2, The Jib Jig, or Rigging track.

Both of these need to sound "fuller", I suppose, with more of a robust sound. I always adore orchestral tracks, but go crazy! Remix them to your desire!
Both links that I have provided will ask you to download the midi file (just a head's up).
