Ahaha, no worries :) The fact that you would come back and play at all makes me happy!
Do you hear the sounds in the headphones when you do that part? There will be sounds to the left, right, or center, and you have to click the corresponding button. Is it just that you keep getting a Game Over screen? (I ask because a few people have also reported having a weird problem occur in this part, so I want to make sure it's just that you keep dying or that something weird is going on). One thing I tell people if they keep dying during this part is that there are no repercussions for hitting the wrong key (you can keep trying other keys until you get it right). So if you start to panic and can't make out the right sounds when the music gets loud, keep trying other buttons quickly until you get it right.
Does that help?
