There were big falls all around for albums by Idol alums on HITS Daily Double's Top 50 building album sales chart this week.

For the first time in a long time, Kelly Clarkson's album All I Ever Wanted slipped to the no. 2 Idol-related entry on the chart, as it slipped #12-23 with 17.8k copies for the week, down 57% from week to week. It was Carrie Underwood's album Carnival Ride that reclaimed that title, taking in 19.3k copies and slipping only 41%. On the chart side, it was only down two spots to #17.

The only other Idol alum to be represented in the Top 50 chart was David Cook, as his self-titled album fell another 58%, bringing in 8.7k copies and falling #28-45 on the chart.
