That's according to Billboard, which is currently running through its end-of-the-year sales charts. As compiled by Nielsen SoundScan, Dark Horse edged out Linkin Park's A Thousand Suns for the top spot.
The chart's fine print points out that sales are for "hard rock and metal albums," lumping the two genres together for tabulation purposes. It may not seem like that big of a deal, but what's funny is that it allows very different-sounding artists like Jimi Hendrix, Breaking Benjamin and AC/DC to all fall into the same category.
While it might be remarkable that a two-year-old album claimed No. 1, it's actually not the only 2008 record in the top 10. The other is Shinedown's equally long-running The Sound of Madness, which came out five months before Dark Horse.
