HITS estimates: Cook 18k; Ruben 14.7k

The Idol finale was kind to some and not to others when it came to HITS Daily Double's Top 50 building album sales chart for the week, as a re-entry led the way among alums.

David Cook's self-titled effort saw a resurgence on the chart thanks to an emotional performance of "Permanent" on last Wednesday's Idol finale, sending the album back into the Top 50 at #26 with 18k copies sold.

Next up was the latest studio album from Season 2 champ Ruben Studdard, as his Love Is made its mark at #34 with 14.7k copies, which is the velvet teddy bear's lowest opening cume to date.

Two more winners followed Ruben, as Kelly Clarkson's All I Ever Wanted slid 26% to 12.7k copies and was done 22 spots to #42, while Carrie Underwood's Carnival Ride saw a much smaller 1% slip to 12.2k copies, down #35-44.

Exact figures will be available as soon as the Billboard 200 chart is made public, which should be later this week.
