Speaking of this nifty data, there's a Midi called "credit wii" that I'm pretty sure doesn't play in game, but then again it's hard to tell because my personal Midi player sounds nothing like the Wii and of course I don't have the game handy to try and find it.
Sounds like a cool song though. Mostly an edit of "Plantation" by my guess.
In the event that it DOES play in the credits and I'm too stunned to notice, Toroko is still in there as midi and I'm almost certain you can't hear it in game. Really this time.
