Predictably, it was a horrible year. But from a certain perspective, the news wasn't all doom-and-gloom. And the Beatles seemed to weather the storm like perhaps only they could.
Excerpt (from the third link):
In a year that featured new releases by U2, Green Day and Pearl Jam, it’s surprising that the year’s best-selling band is, well, no longer a band. As Rolling Stone previously reported, the Beatles’ best-of collection 1 was the decade’s top-selling album, and 40 years after the breakup, the Fab Four were amazingly also the top-selling act of 2009. Thanks to their remastered catalog, the Beatles sold 3,282,000 units in 2009 without the aid of digital music services, placing the group third behind Jackson and Swift and in front of Boyle on the 2009 top-selling artist chart. Additionally, Abbey Road was the year’s best-selling vinyl with 34,000 copies, beating out Jackson’s Thriller and Animal Collective’s Merriweather Post Pavilion. Radiohead, however, was the year’s best-selling artists on vinyl with 45,700 records combined.
