MP3Tunes offers a locker service where users can sync their personal digital music and video up to "the cloud" to access from any web browser or many mobile and home entertainment devices. Recording giant EMI claims that MP3Tunes should be held responsible for infringing content stored in the lockers of some of its users. MP3Tunes contends that it is immune from liability because it does not engage in, encourage or benefit from copyright infringement and it quickly removes material identified in a copyright holder’s complaint against its users, as required by the "safe harbor" provisions in the Digital Millennium Copyright Act (DMCA). In the amicus brief filed Tuesday, EFF and its co-amici argue that EMI is trying to rewrite the "safe harbor" provisions and hold service providers liable for the actions of their users.

Even better the service isn’t all that expensive compared to buying the same amount of storage through something like Dropbox.
