This is the collective reviews from other sites on Wii Music. IGN has a hard standard of a perfect game should be, but their opinion is respectable to some.

1up gave Wii music A-, their site and how they review games is more focus on the emphasis of "FUN" for average avid gamers.
My idea of FUN is very relatively different to others, and I haven't played Wii music yet.
