EMI demanded that MP3tunes provide copies of the more than 100 million songs in their subscribers' personal music Lockers. MP3tunes offers a free and paid service for people to store their music files digitally so customer or music fans can both keep them backed-up and listen to them anywhere through a Net radio, like those from Logitech, Reciva or Terratec, or from any Net connected device, such as a Wii or PC. The newest feature allows subscribers to automatically sync their music files to a device of their choosing so all their music is where they want it to be, without the hassles of running software and plugging devices in via USB cables. All access to a music Locker requires a unique username and password, and there is absolutely no sharing between Lockers.
