best songs ever made?

The best song ever written and recorded is "Since I've Been Loving You". Zep did it a bunch of times, the one I like the best is on Mothership.

Find it, play it, crank it up. Then come back here and tell me it's not the greatest thing you've ever heard.

The Anthrax/Public Enemy version of "Bring The Noise" is a close 2nd.
