It might not be revolutionary, or incredibly innovative, but it was a game changer. It is THE defining epic rock song, that set standars for how to make one. Every rock anthem has to measure up with Stairway. Even the Zepps themselves recognized this as their crowning achievement, and no matter what the hipsters who like to discredit the ones that get considered the best say, this is just perfection put into a record.

The guitar sounds pure, beautiful and heavenly. The drums are subtle and powerful when needed. The bass gives a complete feel to the guitar's heavenly sound. And the vocals are so damn perfect and memorable, he sounds like an angel and a demon on the same 8 minutes. The lyrics are highly poetic, with symbolism all over the place. Everything in the song flows beautifully, the build up is so well done you don't feel like you're listening to an 8 minute song.

Certainly one of the greatest songs in history!
