Carrie Underwood has recorded a cover of Mötley Crüe's 'Home Sweet Home' for the show that launched her career, 'American Idol.' The song will be played every week when contestants are voted off the show, making its debut on March 11. It will also be available for downloading on iTunes, starting on March 16. Underwood is giving a portion of the proceeds to a cause near and dear to her heart, the Humane Society of the United States.

"I've always loved this song, and besides being very fitting for 'Idol,' to me, the title is also very fitting with animal rescue and finding animals their own homes," Underwood says. "So we felt it was important to tie the release into an amazing animal charity like the HSUS."

Underwood won 'American Idol' in 2005. She went on to sell seven million copies of her first album -- the most successful CD to date from an 'Idol' alum.
