Sony BMG has revealed that it will launch a service that lets consumers download music which is free of copy protection software.

The record label said that its new Platinum MusicPass enables consumers to download full-length albums as high-quality MP3 files. These files will not have a Digital Rights Management system, which means that they will work in almost all MP3 players.

"The MP3 files delivered through MusicPass play on computers, as well as on all MP3 players, including iPods," explained Sony BMG's Thomas Hesse.

"This makes them a simple, easy to use solution that will appeal to fans who already access their music on the internet, as well as to consumers who are just getting into the digital realm."

Mr Hesse added that the system was "a great way to bring digital music to the physical retail space" as the cards will be sold a number of retail outlets.

"We believe it will have strong appeal for a broad range of consumers, and that it will ultimately expand both the digital and physical markets for music," he added.

Some of the artists who will be available via the MusicPass include Alicia Keys, Avril Lavigne, Backstreet Boys, Bruce Springsteen, Elvis Presley and Santana.
