The tracks will be offered in MP3 format, without DRM (digital rights management), from Jan. 15 in the U.S. and from late January in Canada.

The move is far from the all-digital service offered by its rivals, though. To obtain the Sony-BMG tracks, would-be listeners will first have to go to a retail store to buy a Platinum MusicPass, a card containing a secret code, for a suggested retail price of $12.99. Once they have scratched off the card's covering to expose the code, they will be able to download one of just 37 albums available through the service, including Britney Spears' "Blackout" and Barry Manilow's "The Greatest Songs of the Seventies."

With election season upon us, Wired News spoke with two of the top computer scientists in the field, UC Berkeley's David Wagner and Princeton's Ed Felten, and came up with a wish list of features we would include in a voting machine, if we were asked to create one.

These recommendations can't guarantee clean results on their own. Voting machines, no matter how secure, are no remedy for poor election procedures and ill-conceived election laws. So our system would include thorough auditing and verification capabilities and require faithful adherence to good election practices, as wells as topnotch usability and security features.
