The reason I wrote this review is because I noticed an overall 4.5 rating on here for this album. This is the greatest hard rock album ever. Period. It deserves a 5 out of 5 for every reason. Jimmy Page is one of the greatest guitarists ever. His riffs and licks are incredible, and his solo for Zeppelin's biggest song, Stairway To Heaven, is still considered the best of all time. The riffs for Black Dog and Rock And Roll are also great. When The Levee Breaks is another highlight of the album. Stairway is still the best song on the record though.

Lyrics kick ass too. Robert Plant's lyrics on Stairway To Heaven are the most deep lyrics I've ever heard. He also provides good lyrics for the rest of the tracks.
Overall Impression — 10
This is the best hard rock album ever (along with Guns N' Roses' Appetite For Destruction and a few others). Anybody should be able to appreciate the great music on this record.
