As expected, Green Day rules the Billboard 200 with 215,000 in sales. The figure is all the more impressive given that it occurred over a three-day period instead of the usual seven-day sales cycle.

The heavily-acclaimed "21st Century Breakdown" is Green Day's second album to hit No. 1, following 2005's "American Idiot."

Making Green Day's top bow even more considerable is "21st Century Breakdown" moves three times that of its closest competitor, the "Hannah Montana" soundtrack, which stays at No. 2 with sales of 68,000 copies. Plus, "21st Century Breakdown" hit No. 1 without the assistance from Wal-Mart. As Billboard notes, the Bay Area trio refused to release a "clean" version of the album and Wal-Mart, therefore, declined to stock the title.  Wal-Mart does not carry albums with parental advisory stickers.

Rapper Cam'ron proves "Crime Pays" as his Asylum/Atlantic album comes in at No. 3, moving 43,000 units. It is the only other new title to debut in the Top 10 of the Billboard 200 this week.

Next week we'll see a different story when a number of debuts will come in the top 10. Eminem's "Relapse" is expected to top the chart, while Green Day's sales will still be strong. Other titles expected to debut strong include new releases from Tori Amos, Lionel Richie and Reuben Studdard. New pop rock band Parachute may also move into the Top 10, but it debuted at No. 39 this week based solely on sales through the iTunes store, which was given a one-week exclusive on "Losing Sleep."

This week's other notable debuts include rapper Paul Wall, whose "Fast Life" comes in at No. 15. Alternative country singer/songwriter Steve Earle debuts at No. 19, the highest chart position of his career, with "Townes," his salute to noted Texas songwriter, the late Townes Van Zandt.
