With so much talent on season 10 of American Idol
– especially during Wednesday's killer rock performances
– it's getting more and more difficult to decide who should stay and who should go.
Haley Reinhart, who's been in the bottom, came roaring back
and impressed the judges again with her Janis Joplin number. Rocker James Durbin slowed it way down with a ballad, which Jennifer Lopez
called "a great choice." And judges' save recipient
Casey Abrams debuted his stand-up bass on the big stage – a definite crowd-pleaser.
Even the judges seem to be digging deeper to find ways of critiquing this crop of outstanding contestants. On Thursday, a thrilled Lopez told Pia Toscano that her performance of "River Deep, Mountain High" was "amazing," but she wanted to push her to study great female artists to fine tune her stage presence.
"It's not that you're not amazing," Lopez said, "but just keep studying, keep researching, get greater." Meanwhile, Randy Jackson declared that multiple contestants are "in it to win it."
So, before Thursday's elimination and announcement of the season's top eight, tell us who you think is the current frontrunner. Vote in our poll below:
