Sony joins EMI and Warner in Apple's iCloud

Apple is collecting the signatures of music industry giants on a daily basis as the Mac maker ramps up to the seemingly inevitable launch of the company's iCloud media streaming service.

EMI and Warner have already reportedly inked deals with the Cupertino company and, today, business news organisation Bloomberg is reporting that Sony has signed on the dotted line.

That only leaves Apple to bag Universal for its cloud-based iTunes-alike, and it has the vast majority of the world's music and film production at its disposal.

The iPod pioneer is expected to to base its over-the-air streaming service at a new billion dollar data centre in North Carolina.

A patent unearthed yesterday revealed that the company may be planning to release new technology which stores a tiny fraction of each media file in a user's library on a mobile device which allows music and video files to be started immediately while the remaining portion of the file is downloaded and seamlessly joined.
