Adele's "21" album stayed atop the Billboard 200 albums chart this week, selling 237,000 copies during the week ended February 12th.  The album is likely to remain on top for a 21st week, with no major albums scheduled for release this week and considering the lift to the singer's popularity from winning six Grammys last Sunday, including Album of the Year for "21".  Coming in at No. 2 on this week's chart was Van Halen's "A Different Kind of Truth," their first with original frontman David Lee Roth since 1984.
