'American Idol': Top 7 Power List!

Way in over his head at this point, Lazaro copped an attitude last week (since when is calling Randy Jackson 'Boo' okay?) and has so much trouble learning lyrics. The idea of him attempting an uptempo rock song is laughable. I can't wait!

'Rock Songs' might be a challenging theme for Amber, who can go uptempo but has mostly stuck to ballads. Last week's judges-standing-O-worthy cover of ''Lately'' was technically great. But can Amber, the only girl to land in the bottom three so far, really rock out?

Burnell's rich tone and unique interpretations are best when he's singing something slow and soulful. He's innovative enough to come up with a re-arranged rock song, for sure -- but have viewers tired of his finger-fluttering flair?

Last week's ''You Better Shop Around'' was an uptempo nightmare, so ''Rock Songs (No Ballads)'' could not come at a worse time for Angie, who's been instructed by the judges to sit at her piano and just sing prettily. With the right guidance, though, a rock cover tailored to her original performance style would be an improvement on last week's aberration. She's still popular.

Does the light-haired Little Marshmallow have dark horse potential? Janelle seemed like a new contestant last week with her own slowed-down rearrangement of ''You Keep Me Hanging On.'' There are plenty of Southern rock hits she could put a country spin on, and she's showed her fearlessness in going uptempo in weeks past.

All we need from Kree is a stronger personal connection to the song -- her ''effortless'' singing style, though lauded by the judges, has made her performances blend together. She and Candice are still well beyond the pack in technical ability, and Kree can definitely rock out.

She's already proven her rock chops with ''Come Together'' and last week's delightfully rearranged ''I Heard It Through the Grapevine.'' With an upbeat theme this week, the huge-voiced favorite should have no problem pulling out another showstopper.
