The Best Song Ever

Don't know which one I like the best, but some songs that are definitely up there are Iced Earth's A question of heaven, Megadeth's Holy Wars, X Japan's Blue Blood and Ozzy's Diary of a madman. I guess it differs depending on my mood.
 
I second A Question of Heaven by Iced Earth. I also throw in Master of Puppets by Metallica and Learning to Live by Dream Theater. One of those three for me, depending on the day.
 
black sabbath - black sabbath, because it started everything

i will never ever get tired of listening to holy wars either. perfect
 
My top five:

Jimi Hendrix - All Along the Watchtower
Iron Maiden - Rime of the Ancient Mariner
Iron Maiden - Phantom of the Opera
The Rolling Stones - Sympathy for the Devil
Red Hot Chili Peppers - Californication - My favorite song to listen to during the summer when I go for my morning run.
