Everyone’s favorite internet behemoth today detailed plans for their initial foray into the rapidly-expanding world of cloud-based music services. Google music joins Amazon’s cloud player in providing means for users to upload their music libraries to the “internet”, to be accessed from any computer or mobile device they choose. Google’s offering will allow users to upload up to 20,000 tracks, far superior to Amazon’s 5GB but lacks the ability (at present) to actually sell music directly. User libraries can be accessed from any desktop or Android-powered mobile device. Head over to the official site to request a beta invite, or hang tight to see what Apple have in store.
