The Trick is NOT everlasting. After awhile the game will not let you slow it down anymore and will progress you through no matter what. I failed like 5 times at a song, constantly using the slow it down method and then when I tried to get the slow it down thing to show up, it absolutely refused. There is a limit to how many times you can do that...
What do you see, when you look at me? That I'm angry? That I could hurt you? It must be my eyes...creeping along your body, you can feel the death waiting for you in my eyes.
