Thriller25 Blocked From The Pop Chart

When is the second highest selling album of the week nowhere to be found in the top 200?

There used to be a number of reasons but now it’s down to one: When the disc has been classified as a catalog release.
The 25th anniversary edition of Michael Jackson’s "Thriller" (Epic/Legacy) sold 166,000 copies in its first week of release, which would make it the second biggest seller of the week that ended Sunday.
