Who’s ready for a 90-minute laser light show?! Tonight’s top 4 X Factor performance episode will once again cram in two performances from each of our remaining “acts.”

Instead of a four-slide Power List, this week I did a photo gallery of the Best and Worst efforts from Marcus, Chris, Melanie, and Josh. Read that here, and name your own Power List below!

Here’s mine, for the record:

4. Marcus Canty

3. Chris Rene

2. Melanie Amaro

1. Josh Krajcik

SHE’S BACK! American Idol season 6 alum Melinda Doolittle will be here for tonight’s top 4 performance show! Melinda and I will be cohosting’s live chat of The X Factor beginning at 8 p.m. ET. If anyone knows what it’s like to “leave it all out on the stage” for Simon and Paula, it’s Melinda. Don’t miss it.

For now, take a listen to Melinda’s new Christmas single “God Bless Us Everyone,” embedded below. It’s gorgeous and timeless and getting a lot of radio play already — “probably because it has ‘God’ in the title,” Melinda astutely surmises.

Visit for official updates (including new tour dates, pics, video, M.D.’s tweets, and much more).

See you at tonight’s live chat!
