I watched the vids on IGN, and there is definitely Mario music in the game. That's sort or the whole point, isn't it? One of the four videos had a (quite good, thankfully) remix of the music from Super Mario Brothers 2 (the same tune that's in SSBM). According to IGN, the game also features some rendition of the original Super Mario Brothers theme, but I didn't recognize it in any of the videos. One of the videos had a (not so good, unfortunately) version of Bizet's Les Toreadors part I from Carmen, and another had a decent version of Mozart's Eine Kleine Nachtmusik, so the game won't feature only Nintendo music. I happy about that, because as much as I love Nintendo music, I also appreciate variety.
I know of one other dance game for GameCube. It is called MC Groovz danceCraze, it features a dance pad, and it is currently released in the US. However, it was published by MadCatz, a company that has never made software before (to the best of my knowledge) and is notorious for making poor quality hardware. Somehow I'm guessing MC Groovz isn't all that hot. IGN hasn't even bothered to review it.
