This game has a pretty good soundtrack by virt / Jake Kaufman. Haven't found a downloadable rip yet, but at least it's listenable on soundcloud:

Some of my favorites are "I Am So Determined You Have No Idea", "Chores And Other Scary Stuff" and the Boss Theme. They set a nice mood in an otherwise very tongue in cheek game. Unfortunately, the music in the DS version is compressed compared to the 3DS version, so if you're interested in the game, go for 3DS if that's a possibility.
