What is your favorite song of all time, mine is either Nem Vem Que Nao Tem by Wilson Simonal (that featured in the Ikea advert, with all the changing furniture and moving walls) or Jerk it Out by Ceasars Palace
Of all time? Probably Slipknot's "My Plague" from the Iowa album. It was the first real metal album I bought, and it blew my head away. It introduced me to a whole new genre, and from that I got into other bands of the same/heavier genre.
