@koopaul,
Well, he was also trying to get them to fit the characters. Peach doesn't get drums because it doesn't fit her well. Ridley's lack of a "real" song provides an eerie feeling that goes pretty well with his character (anything else would make it sound like you're still fighting). With Wario, the "nya nya nya" fits his absolute silliness that he acquired from the WarioWare series.
With Samus and Fox, the two have very heroic themes because, they are the heroes.
With your suggestion for Yoshi, I'd have to say I like that one just as much as the Yoshi's Story Results Screen theme, so I can't really choose.
@Gary, AC's song actually sounds okay. I can't exactly say what could improve it; it just sounds less epic and grandiose than the others.
