Nine Inch Nails [ tickets ]' Trent Reznor is letting fans take a crack at retooling "The Hand That Feeds," the first single from the group's forthcoming album, "With Teeth."

Those interested can visit NIN's website, where Reznor has posted a downloadable version of the song formatted for use with Apple Computer's GarageBand recording-studio software.

"For quite some time I've been interested in the idea of allowing you the ability to tinker around with my tracks--to create remixes, experiment, embellish or destroy what's there," Reznor wrote in a message that accompanies the download. "... Change the tempo. Add new loops. Chop up the vocals. Turn me into a woman. Replay the guitar. Anything you'd like.

"I'm interested to see what comes of it, what issues are raised and what the results are. Have fun."
