This week’s overall national album sales were the lowest ever in Soundscan history, with only 4.95 million records sold — period. That means that, since its release, AC/DC’s Back In Black has sold over four times as many copies as every other album ever recorded by every artist ever who sold an album in America last week. It also means that if this were to have happened ten years ago, when ‘N SYNC’s No Strings Attached debuted at number 1 with 2.4 million copies sold, every other album ever recorded by every artist ever would have only sold a cumulative 2.55 million copies between them.

But remember when home-taping was killing the record industry? Yeah, that was cute.
