LMAO! (Boogie Ooogie Oogie at #2 doesn't say much either!)
The list was more than likely compiled by sales of

A More Realistic Top 100 Albums as voted by actual listeners. Led Zeppelin IV properly holds the position of #1

with Queens's "A Night At The Opera" in spot # 81.
You'll find plenty of Beatles and more modern rock albums in the mix.
