Pia Toscano, Lauren Alaina, Thia Megia highlights among "American Idol" top 12 women

(CBS) The boys had their chance on Tuesday. Now, it was the ladies' turn to sing.

The 12 female contestants took to the stage on Wednesday night's "American Idol," to varying degrees of success.

Ta-Tynesia Wilson started the night off on a mediocre note, with her rendition of Rihanna's "Only Girl in the World." "It wasn't unbelievable," Randy Jackson told her, while Jennifer Lopez started her critique on a blunter note: "It's good that it's over."

Naima Adedapo sang a jazzy version of "Summertime," which Jackson called "lounge-acty," Rachel Zevita overdid it while singing Fiona Apple's "Criminal" and Julie Zorrilla drew unfavorable comparisons to first "Idol" champ Kelly Clarkson when she sang "Breakaway."

But they weren't all bad. Thia Megia shined with her no-fuss performance of "Out Here On My Own," Lauren Alaina played to her strengths with a rendition of Reba McEntire's "Turn on the Radio" and Lauren Turner's performance of "Seven Day Fool" was declared "a perfect, full complete sentence" by Steven Tyler.

But the best by far was Pia Toscano, who brought the house down with her version of the Pretenders' "I'll Stand by You," which got a standing ovation from all three judges.

"Idol" will announce the season's finalists on Thursday.
