Kerrang! Magazine are ready for you to tell them what you think is the greatest rock song ever. You can vote for up to three songs and tell the magazine why they deserve to be above the rest. While most bands only have one song to choose from Avenged Sevenfold have two with “Beast And The Harlot” and “Nightmare.” That should leave you with only one space to fill, if you choose to. The results will be shown on Kerrang TV! on Good Friday (April 6th). After voting you’ll be entered to win an Fujifilm digital camera, Sony DVD home cinema system and a Song 32-inch widescreen HD TV. Winner will be chosen at random after voting has closed on midnight April 1st. Full terms and conditions can be found at the source.
