This is the real epic on Led Zeppelin IV. "Stairway to Heaven" may be good the first 100 times you hear it or so, but this song never gets old. It has everything that makes Led Zeppelin great, with it's lyrics about Dark Lords and it's minstrel-song feel, along with Robert Plant's typical impassioned vocals. Led Zeppelin may be one of the more over-hyped bands of all time, but sometimes the hype was deserved. This song is definitely one of those cases.
