Despite rampant speculation this past week that Britney Spears' Blackout would debut atop The Billboard 200 album chart, it didn't. Who was the dark horse that snatched her much needed glory? Classic rockers The Eagles, who sold a whopping 711,000 copies of Long Road Out of Eden exclusively at Wal-Mart. But if it wasn't for a last-minute chart change, their seismic sales would have been totally eclipsed by Britney. Here's what happened…

Prior to Tuesday night, when the final chart positions were calculated, Billboard basically ignored albums that were exclusively sold at Wal-Mart, leaving them off of The Billboard 200, mainly because the retailer refused to release its sales data. But, literally at the 11th hour, Wal-Mart decided to hand over its sales info for The Eagles' album, which bumped Britney from the top of the chart.

So … was Britney robbed of the #1 spot? You tell us...
