Here's a look at American Idols on the album chart (and a couple that have fallen off), courtesy Nielsen SoundScan:

Number-one last week: Dreamgirls featuring Jennifer Hudson (66,000, down 36% from the previous week; 452,000 total): Of course not technically a J-Hud (wow, hope that doesn't catch on) album, but she deserves to share in the credit.

Number-three: Daughtry (56,000 sold; down 27%; 1.18 million total): Great jump, although it was due to his rate of decline was the only one among the top 10 albums that was lower than the overall drop in album sales (which was 34%).

Number-19: Carrie Underwood (39,000 sold; down 41%; 5 million total)

Number-47: Taylor Hicks (19,000 sold; down 51%; 559,000 total): Everybody was down, but Taylor dropped significantly.

Number-66: Fantasia (14,000 sold; down 37%; 231,000): Essentially held its own considering the general downtrend, and the single's still alive, but it's a long way from gold.

Number-83: Kellie Pickler (10,600 sold: down 36%; 363,000): Also holding its own. Three months to 500,000 at this pace.

Katharine McPhee: No. 3 on the singles chart with a staggering 600 copies; total 158,000.
