If both are targeted at casuals, then Wii Music will beat LBP Casuals don't go online and read reviews or check gameplay footage. They're going to hear the name "Wii Music" and think "Oh, it's a wii game, and you make music. Sounds good". And they're going to hear the name "Little Big Planet" and think "Umm... It sounds like something my Cousin, who loves Halo, would like... I'm getting Wii Music."
Even a lot of people on this very forum, the last bastion of the hardcore, have no idea what you actually do in LBP. The best explanation I've heard is 'It's kind of like a platformer, only you get to make your own levels and the graphics are silly and awesome'.
OTOH, if LBP is for the hardcore, it'll sell fine.
Wii has more 20 million sellers than PS3 has 5 million sellers.
