No. 8 (Girls): Kady Malloy's "Magic Man" (and staircase entrance) failed to impress last week: she'll have to step it up to stay in the running.

AI-PowerRanking-Amanda-Overmyer7
No. 7 (Girls): Amanda Overmyer's hair was the most memorable thing about her "Carry on Wayward Son." The rock-and-roll nurse has to show some major improvement to avoid being discharged soon.

AI-PowerRanking-Danny-Noriega8
No. 7 (Guys): Of the guys, Danny Noriega fell the furthest this week, dropping three spots in our Power Rankings. Could his attitude toward the judges be hurting his chances

AI-PowerRanking-Asiah-Eppererson6
No. 6 (Girls): Asia'h Epperson tackled a big song this week in "All by Myself," and it tackled her back; she had a hard time with the chorus and should focus on song selection in the future.

AI-PowerRanking-Luke-Menard6
No. 6 (Guys): Luke Perry/Orlando Bloom look-alike Luke Menard gave a poppy performance of Queen's "Killer Queen" for '70s week.

AI-PowerRanking-KristiLee-Cook5
No. 5 (Girls): Kristy Lee Cook had the biggest tumble in our Power Rankings among the girls, dropping three spaces. The horse trainer and tomboy seems to be just coasting for now.

AI-PowerRanking-David-Cook5
No. 5 (Guys): Rocker David Cook gave a rousing rendition of "All Right Now" last week, and his revelation that he's a "word nerd" who enjoys crossword puzzles endeared him

AI-PowerRanking-Syesha-Mercado4
No. 4 (Girls): Syesha Mercado received criticism from the judges for the gender-flopped version of "Me and Mrs. Jones" she performed, but her vocal skill and charming personality have kept her in the running.

AI-PowerRanking-David-Hernandez4
No. 4 (Guys): The biggest rising star among the guys, David Hernandez climbed four spaces in our Power Rankings since last week, thanks to his sizzling performance of "Papa Was a Rollin' Stone."

AI-PowerRanking-Ramiele3
No. 3 (Girls): Dropping two spots since last week, petite vocal powerhouse Ramiele Malubay - who sang a disco classic for '70s week - may be proving that her strength is ballads rather than upbeat numbers.

AI-PowerRanking-Jason-Castro3
No. 3 (Guys): Shy-guy heartthrob Jason Castro chose to sing with his guitar again last week, but his "I Just Want to Be Your Everything" was hardly music to the judges' ears (Simon called it "schmaltzy").

AI-PowerRanking-Carly-Smithson1
No. 2 (Girls): Carly Smithson, who moved up four spots in our Power Rankings, is proving herself to be the girl to beat; she showed serious Heart with her rendition of "Crazy on You."
14 of 16 Michael Becker/Fox
AI-PowerRanking-Michael-Johns2
No. 2 (Guys): Michael Johns gave what Simon called his worst performance on "Go Your Own Way." His good looks and charisma can carry him far, but will he be able to compete with the No. 1 guy

AI-PowerRanking-Brooke-White2
No. 1 (Girls): By channeling Carly Simon, Brooke White climbed four spots with her "You're So Vain." Simon was pretty sure the song was about him, and who are we to argue

AI-PowerRanking-David-Archuleta1
No. 1 (Guys): With a whopping 63.6 percent of the guys' Power Rankings votes, 17-year-old sweetie pie David Archuleta is definitely the early favorite. His "Imagine" even made Paula cry.
