Did you ever wonder what tunes Britney Spears works out to? What about Ellen DeGeneres' playlist? Now, Tonic Media is giving you the chance to see for yourself.
Tonic is auctioning off over 70 iPods signed by celebrities, and preloaded with each star's favorite songs.
All of the proceeds of the auction will be given to Music Rising, an organization that replaces lost or destroyed instruments in the hurricane-affected Gulf Coast region. For more information, check out Tonic's website here.
