Nintendo is really interested in advertising Wii Music in Japan. There are television ads in the Tokyo subway which show various potential customers playing the game. But, weirdly, there's not much official information regarding the tracks that will be included in the retail disk of Wii Music.

The tracks which have been officially revealed until now are: My Grandfather’s Clock, which is an old bluegrass song, Eine Kleine Nachtmusik, Ode to Joy, Super Mario Brothers Theme, The Legend of Zelda and Animal Crossing Wild World. It's interesting to see that the game will mix tracks which are taken from Nintendo's history with some having an international appeal. At the moment, it's not clear whether the North American and the European versions of Wii Music will have the exact same track composition as the version which is set to launch in Japan.

It seems that the first three songs are also covered by J-pop singers and that these versions might make it into the game and not the original ones.

Wii Music is the casual Nintendo powered answer to the success that both the Guitar Hero series from Activision and the Rock Band franchise from MTV Games are enjoying. Wii Music will not incorporate vocals and it not set to be a music simulation game, but a game in which music can be created even by those uninitiated in playing an instrument.

Recent demonstrations of the game emphasized the way you can use each instrument individually to produce songs rather than on covering already existing tracks. A complete track list will probably be available once the game launches in Japan. Nintendo has been criticized by some of its hardcore fans for failing to deliver more interesting games and Wii Music has been cited as an example of how the company is creating titles considered too casual. Including theme songs from Legend of Zelda and Super Mario might be an attempt to appease those long time fans.
