Query: Hello, I'm from the future...

I'm here to warn you NOT to buy this CD. Two days from now, you do buy this CD.A month later a friend finds out you have the same CD as his pimple-face sister. He tells all your other friends, and they exile you from all that is cool.As a result of not having any friends your social skills plummet, and you end up not being able to get any jobs. Within 3 years you starve to death wearing only a fairy-godmother outfit and a pair of combat boots.10 years from now the world is taken over by angry pimple-face sisters. Thats the problem, we need you to save the world.So please - for the sake the planet, don't buy this CD. Thanks, sorry to slow you down. See you in 10. *vanish*
