The epic run of Pink Floyd's 'Dark Side of the Moon' on the Billboard 200 albums chart ended long ago, and you won't find the 1973 classic on the magazine’s current Catalog Albums chart, either.

But don’t feel sorry for the legendary British band: 'Dark Side' still sells, at worst, an impressive 10,000 copies per week.

'Dark Side of the Moon' spent a whopping 736 weeks on the Billboard 200 between 1973 and 1988. With a remastered, extras-filled version of the album due Tuesday, September 27 as part of a massive Floyd catalog campaign, a return to the chart is very likely.

"It's all going out under the title 'Why Pink Floyd?'" drummer Nick Mason recently told the Irish Times. "It starts with 'Dark Side,' and then all the other albums get the same treatment over the following months. It's a massive project, and the reason myself, [guitarist] Dave [Gilmour] and [bassist] Roger [Waters] got together to do this was because we really think this will be the last throw of the CD dice."
