Kelly Clarkson's 'Stronger' Album Sales Up 51% Post-Grammys

Several albums saw big sales gains following Sunday night's Grammy Awards, but most American Idol acts didn't get to participate in the bounty. After singing with Jason Aldean on the telecast, Kelly Clarkson saw weekly sales of her Stronger album climb 51%, but no other Idolact on the Billboard 200 saw increased sales last week, according to Nielsen SoundScan.

The Civil Wars, whose Joy Williams has contributed songs to David Archuleta's albums, look to be the breakout act from the show. Week-to-week sales of the duo's Barton Hollow album nearly tripled after they performed an abbreviated version of the song Sunday. Six-award winner Adele, of course, won big again, as sales of 21 nearly doubled from the previous week. Her debut album, 19, also climbed back into the top 10.
