Billboard has decided to revise its chart policy and will include albums sold at exclusive locations (ie Walmart), which means that The Eagles have taken the top spot on the billboard charts, not Britney Spears.

The Eagles, with their album Long Road Out of Eden have taken the top spot, selling 711,000 copies, moving Britney's Blackout to number 2, selling 290,000 copies.

I still say she sold a lot more than I thought she would.
