Using a "Mega X-Key". A little device that connects out of the controller port to input info and also has a USB connection to store it on your PC. My bro got one for �19.99 from http://www.lik-sang.com It works brilliantly!!!
Chaveza, I'm sorry I got it wrong. The mega x key can only transfer/back up game information not music. Probably a microsoft securtiy/copyright feature. But the device is still useful to copy and back up etc.
