Judging by the success of games like Rock Band, everyone wants to play music. Traditional music tuition isn't suited to most people, since you start with pretty dull material, and you don't get results until you've been at it for a while.

That's what all learning should be like. It fits the $2 impulsive-app-purchase model pretty well, and it works for any skill level.
