Wow. This ranks very highly in my list of threads I never knew I always wanted.
This game also ranks very highly in my top Gamecube games of all time. Seriously, the bongo controls made this game great. Fuck the 'should have used the Gamecube controller' zealots.
Super stylish, rad music, and one of the best gameplay mechanics ever conceived in a platformer. The combo system and medals seriously kicked up the replay value of this game 10-fold. Also, the one-on-one boss battles were fantastic, and made Donkey Kong a total badass. The variety in gameplay makes the pacing of this game so fantastic. Each stage offers something different.
Seriously, if you haven't played it and you have completionist compulsions, give it a shot. It's a top class game.
