If Hell could be converted into sound I believe it would sound exectly like Raining Blood by Slayer.

The song is so fast, so evil, so heavy and so great that whenever its on you feel like satan is going to apear and rip out your soul, but in a good way. You almost if not definitly do want that to happen. When its on you have to look around to check where you are and not in the pits of hell surrounded by fire and evil, althought I wouldnt hate that.

It doesnt get any more evil or angry. Slayer will always hold a special piece of my heart, that black rotted hole that is left by their evilness.
