Does anybody know a site to check top album sales? (DSOTM!!!)

[Villavic]

I just saw classic albums-DARK SIDE OF THE MOON (Pink Floyd). It says it was (I heard it before, too) 750 weeks on charts. Now that's a huge record. With all those weeks.. how come it's not the top in history? Is it in top ten? When radios comment about top albums in history, they usually mention SNFever, Grease, Eagles GH-1, Rumours, and of course, the #1, Thriller. But not always I hear about DSOTM.

Of course sure at week #500 probably it was not on top 40, but sure on top 100 and that's a considerable amount of sales, sure!

Is there awebsite to see the official top albums in history? Are there including also worldwide statistics?
