You might recall when a slew of Michael Jackson albums became relegated to the Top Pop Catalog chart following his death in June, due to the previous rules. (Billboard had previously gone by the mantra stipulating "that an album that ranks below No. 100 on the chart, is more than 18 months old, and does not have a current charting single at radio, would be removed from the Billboard 200 and other corresponding album charts on which it has appeared.")
And you can only imagine the legions of angry Jacko fans who weren't having any of that.
