From NPR:

Morning Edition, November 8, 2007 – The power of Wal-Mart can now be measured on The Billboard 200 music chart.

The Eagles are No. 1 this week. Their new album Long Road Out of Eden almost didn’t make the trip to the top because of Billboard’s longstanding rule that albums must be sold in more than one outlet. But, if that one outlet is Wal-Mart, just maybe that rule could be changed. And this week it was changed, bumping Britney Spears Blackout from the top spot.

Personally, I like WalMart. They save me a lot of money.
