Pia Toscano called 'murderer!' on 'American Idol'

Pia Toscano is next on "American Idol" singing "River Deep, Mountain High." She thinks she's gonna shock everyone tonight with something up tempo. Uh, OK. She's kind of talked about it a lot....

You can tell Gwen Stefani dressed her tonight. She has that glam rocker chick look complete with rings around her neck. She's not bad actually. She's got a pure tone. Her habitual angry demeanor works here. 

Man, she has the pipes, and the confidence. It's all a bit ragged, feel like she's moving from set piece to set piece, but what a voice.

"Murderer! Murderer" yells Steven Tyler, "you killed it!"

Jennifer Lopez says "you're really special up there." She wants her to start studying the great performers to work more into her style. 

Randy Jackson says she delivered and echoes J.Lo that she needs to work on her movements.
