are the notes supposed to come in huge spaced bursts?

Given the nature of the game, I would have figured that the beatbox part
would be the sound effects of pressing the buttons
instead of being a layered track, so that the player can get a feel of when to properly line up the notes.
Right now it makes for somewhat weak feedback during the beatbox
part and none at all during the box-eating part.

Neat concept, though. Could be interesting to see it iterated upon.
