Green Day has the most popular CD in the country, but you won’t be able to find it at your local Wal-Mart. According to the Associated Press, the band says the chain refused to stock their latest CD, 21st Century Breakdown, because Wal-Mart wanted the album edited for language and content, and the band refused. Even though the album is not available at the store, it still sold over 215-thousand copies and debuted at the top spot on the Billboard album chart.
