We always dread when an American Idol contestant chooses to sing a Whitney Houston song on the show, since there’s an above average chance that their performance will pale in comparison to the real thing. But on next week’s performance night, the Idol ladies in the Top 13 won’t be able to sing anything but songs from Houston’s songbook. As for the boys, they’ll take on Stevie Wonder’s tunes — but wouldn’t it be more fun if it was the other way around? Though this is obviously a smart move on Idol‘s part to tie-in with the public’s piqued interest in Houston’s music since her death, we predict this to be an incredibly challenging night for the girls. Okay, folks, let us know — which female has the pipes to pull off “I Will Always Love You”?
