Peak Moment to Date: Showed off a rich, powerful tone on Sheryl Crow's ''If It Makes You Happy'' while strumming the guitar and breaking out the harmonica.
Achilles' Heel?: Certain segments of Idol fans are notoriously tough on rocker chicks, women with tattoos, and single mothers.

Peak Moment to Date: His strangely sexy audition to ''Let's Get It On'' has already scored him a fanbase called ''Grady's Ladies,'' and his retro-cool vibe should be fun to watch juxtaposed with Idol's cheesy machinery.
Achilles' Heel?: Producers pretty much ignored him throughout Hollywood Week. WTF? (Why the face?)

Currently Resides: Miami, FL
Peak Moment to Date: Served up a sexy ''Chain of Fools'' in an Idol season 9 promo.
Achilles' Heel?: Aside from a four-second solo singing ''Irreplaceable'' (with Ashley Rodriguez and Charity Vance) during group rounds, she's been season 9's invisible woman.

Currently Resides: Sonestown, PA
Peak Moment to Date: Improved on Miley Cyrus' original when he performed ''The Climb'' in Orlando, and his ''yes, ma'am'' charms will play well with fans of squishy teenage contestants.
Achilles' Heel?: Flubbed his lyrics not once, but twice, after scoring a Golden Ticket; at the tender age of 16, we're not sure he's ready for this jelly.

Currently Resides: Chelsea, MA
Peak Moment to Date: Got dubbed an early front-runner thanks to a solid cover of ''If I Ain't Got You'' during Idol's season 9 premiere.
Achilles' Heel?: Has the voice and the look, but hasn't yet shown the inventiveness it takes to win the competition in a post-David Cook era.

Currently Resides: Arlington, TX
Peak Moment to Date: Of the umpteen renditions of ''I'm Yours'' during the Hollywood rounds, Todrick's showy, inventive take (featuring flourishes of falsetto and growl) was the best.
Achilles' Heel?: Most of his interview footage — getting snippy as part of ''Destiny's Wild,'' macking on bikini babes while lounging poolside — has been Rated A...for Annoying!
7 of 24
Hometown: Tampa, FL
Currently Resides: Tampa, FL
Peak Moment to Date: Delivered a knockout, folksy twist on ''American Boy'' during Day One of Hollywood Week, but that sumptuous audition snippet to ''House of the Rising Sun'' remains her crowning achievement.
Achilles' Heel?: Final Hell Week performance of Taylor Swift's ''Love Story'' was kind of a mess, with Janell admitting she couldn't handle the pressure. Will she crack when she has to perform live for 25 million people?

Peak Moment to Date: The rich, sexy baritone he showed off on Blood Sweat and Tears' ''I Love You More Than You'll Ever Know'' left Shania Twain drooling like a Pavlovian canine.
Achilles' Heel?: Lone Hollywood Week footage included John's voiceover expressing vague disappointment with his performance.
9 of 24
Hometown: Cape Cod, MA
Currently Resides: Marstons Mills, MA
Peak Moment to Date: Thirty-second snippet of Hollywood Week solo on ''Living for the City'' proved she's got as much vocal horsepower as any woman in the competition.
Achilles' Heel?: Siobhan's frocks have veered from granny garish (a heavy white-lace top Ellen described as too old) to gimmicky '80s kitsch (newsflash! only Dancing With the Stars' Edyta Sliwinska is allowed to wear legwarmers in prime time!).

Hometown: Duncanville, TX
Currently Resides: Duncanville, TX
Peak Moment to Date: Impressive mop of hair and last-minute semifinal substitution for disqualified Chris Golightly are his current claims to fame.
Achilles' Heel?: His butchery of David Cook's ''Come Back to Me'' will not please season 7 loyalists.
11 of 24
Hometown: Amarillo, TX
Currently Resides: Amarillo, TX
Peak Moment to Date: A top 50 contestant in season 8, her ''Over the Rainbow'' was a definite highlight of the talent-packed ''Road to Hollywood'' audition episode.
Achilles' Heel?: Her subtle style — that Hollywood Week rendition of ''What a Wonderful World'' occasionally dissipated to a whisper — might work against her when she's backed by Idol's ''Bandzilla.''
12 of 24
Hometown: Fort Worth, TX
Currently Resides: Fort Worth, TX
Peak Moment to Date: Made a big splash taking off his shirt for Kara, but it was a bluesy ''I Don't Need No Doctor'' on Day 1 of Hollywood Week that proved he's got a legit shot at the season 9 crown.
Achilles' Heel?: He can sing for sure, but both his audition and his Hell Week cover of ''Bubbly'' betrayed a lackluster stage presence that could get exacerbated on Idol's big stage.
13 of 24
Hometown: Littleton, CO
Currently Resides: Denver, CO
Peak Moment to Date: Wasn't shown during the audition rounds, but her nuanced, acoustic cover of ''Lullaby of Birdland'' on Day One of Hollywood Week turned her into an instant contender.
Achilles' Heel?: Pushed her vocals too hard on Hall and Oates's ''Rich Girl'' for her final Hell Week performance; needs to remember that the show has evolved past its former ''bigger is always better'' ways.

Currently Resides: Astoria, NY
Peak Moment to Date: Personal trainer has the jauntiest personality of the season 9 crop — loved that shuffle-y dance after he cracked the top 24 — and scored plenty of screentime after his wife gave birth during his Hollywood run.
Achilles' Heel?: ''She's at eight centimeters!'' Seriously, dude? Also, his acoustic version of ''I'm Yours'' threw up a red flag about problems with breath support and pitch.

Currently Resides: Fort Collins, CO
Peak Moment to Date: It was almost impossible not to be charmed by her zippy audition to Carrie Underwood's ''Last Name.''
Achilles' Heel?: It was almost impossible not to be appalled by her botched lyrics to ''Sweet Escape'' and botched notes on ''I'm Yours'' during Hell Week. Needs to pull it together — pronto! — or this adorable kid will be the first one swept overboard this season.

Peak Moment to Date: Brief audition snippet of ''Ain't No Sunshine'' (which was presented side-by-side with Crystal Bowersox's ''Piece of My Heart'') showcased a hot, gruff vocal.
Achilles' Heel?: Botched the intro to the chorus of ''You Found Me'' in his final performance — and that lackluster rust cap and blue t-shirt weren't exactly screaming ''music superstar,'' either.
17 of 24
Hometown: Naples, FL
Currently Resides: Houston, TX
Peak Moment to Date: As Simon sent her through to the top 24, he told Paige she was a better vocalist than she realized.
Achilles' Heel?: Other than a brief flash of her doing backup vocals on Neapolitan's a capella ''Bad Romance'' (in which she didn't even get identified!) Paige has been largely absent from the season 9 proceedings. Do the producers realize she is auditioning for Idol, not Without a Trace?

Currently Resides: Moreno Valley, CA
Peak Moment to Date: His acoustic twist on Paula Abdul's ''Straight Up'' was one of the best Hollywood Week performances in Idol's nine-season history.
Achilles' Heel?: It's always dangerous to peak too early in the competition; Idol voters love to see growth as much (if not a bit more) than consistent excellence.
19 of 24
Hometown: Knoxville, TN
Currently Resides: Los Angeles, CA
Peak Moment to Date: Wowed the judges in Hollywood with a gorgeous rendition of the Kara DioGuardi-penned ''Terrified.''
Achilles' Heel?: Near-constant crying and relentless references to deceased friend could quickly go from affecting to annoying.
20 of 24
Hometown: Huntington Park, CA
Currently Resides: Huntington Park, CA
Peak Moment to Date: Didn't hit any bum notes during a 10-second, blink-and-miss cover of ''Man in the Mirror'' during Hell Week.
Achilles' Heel?: Near total airtime shut-out makes him potential semifinal cannon fodder, unless, as Randy might say, he ''blows it out the box, dude!''
21 of 24
Hometown: Middlebury, CT
Currently Resides: Middlebury, CT
Peak Moment to Date: Her Boston audition performance of ''At Last'' was powerful and in-tune, and possessed an elegance and depth impressive for so young a vocalist.
Achilles' Heel?: The show's relentless mentions of her Alzheimer's-afflicted grandmother have threatened to overshadow Katie's vocal talents. J'enough!
22 of 24
Hometown: Fort Worth, TX
Currently Resides: North Richland Hills, TX
Peak Moment to Date: Survived working with she-beast Mary Powers performing Fleetwood Mac's ''Dreams'' in the group round; name similarity to a rather popular season 8 finalist might win him a few votes, too?
Achilles' Heel?: His ukelele showed more charisma than he did during his paint-by-numbers rendition of Jason Mraz's ''I'm Yours.''

Currently Resides: West Des Moines, IA
Peak Moment to Date: Shania Twain said her audition to ''Syrup and Honey'' showcased the kind of voice that could make a hit record.
Achilles' Heel?: Simon and Ellen both criticized Katelyn's Hollywood Week performances; is it possible she's being pegged for the Kristy Lee Cook/Haley Scarnato ''pretty girl punching-bag'' slot?
24 of 24
Hometown: Joliet, IL
Currently Resides: Joliet, IL
Peak Moment to Date: His audition, a soulful and sweet reworking of Joan Osborne's ''One of Us,'' was intriguing and unexpected.
Achilles' Heel?: Has a tendency to indulge in showboat-y vocals; that glory note in ''Carry On Wayward Son'' during the group round was as subtle (and enjoyable) as a kick to the groin.
