CARLY SMITHSON
There's not been a female rock voice this alluring since Ann Wilson, and 24-year-old Carly's watertight version of Heart's ''Crazy on You'' during '70s Week proved it. The judges can grouse about song selection all they want — what matters isn't the tunes our tattooed Irish bartender picks but the way they glide like Guinness from her gifted throat. Consider her domination of ''Alone'' during Hollywood Week: She pulled it off without breaking a sweat, and anyone who's ever tried to karaoke that sucker knows it shouldn't look that easy. (And her take on ''I Drove All Night'' showed she can transcend the Heart catalog.) All the effortless talent of Melinda Doolittle with none of the cloying lack of confidence? If anyone's poised to stop Archuleta's march to the title, it's Carly. —Whitney Pastorek
