Fan Fare

Curious about what your favorite singer listens to on their iPod?

Here comes a chance not only to find out, but to buy the personal playlist and the autographed iPod of 70 celebrities ranging from Madonna and Beyonce to Carrie Underwood, Britney Spears and fashion designer Marc Jacob.

Philanthropic Web site Tonic.com is auctioning off  between one and five of  the signed iPods every week from now until August and sending all the money directly to benefit Music Rising — an organization that replaces musical instruments that were lost or destroyed by Katrina and other hurricanes in the Gulf Coast region.

First up is Mariah Carey (clearly a big hip-hop fan), Gwen Stefani whose tastes range from Prince to Joni Mitchell, country star Faith Hill (who seems to have a fondness for someone called Tim McGraw?!) and Pete Wentz ( Mamma Mia! and the musical Wicked!??).
