Pia Toscano is a Murderer on American Idol

Pia Toscano murdered Tina Turner's classic "River Deep, Mountain High" on American Idol last night. That's meant as praise by Steven Tyler - she rocked!
"Murderer! Murderer! You killed it!" Steven says.
Not to be confused with butchering it, which would imply a poor effort, Pia Toscano absolutely killed. Her inspiration for taking a page out of Tina's book?
"I want to shock everybody," she says, "'cause I've been doing the whole ballad thing."
Safe to say she succeeded in the best way with a powerful, self-assured, uptempo rendition. It was just a winning performance from a pro all around:

"I'm going to keep pushing you," J-Lo said, saying she still must continue to do better. "You are spectacular, but just keeping studying, keep researching."
If that's the worst criticism lobbed at you, you're doing awfully well.
