I’m sure you’ve read about Google’s online music service, appropriately titled Google Music. If you haven’t, it’s Google’s online music store and it’s also a free service which allows you to upload up to 20,000 of your own music files to Google’s cloud. Then, it allows you to listen to both purchased and uploaded songs from any browser (Windows or Mac PC) or through the Google Music app on Android devices. It’s Google’s answer to Apple’s iCloud and Amazon’s Cloud Player.
Unfortunately the service is currently only available within the US, and although Google will successively begin offering the service to other countries, if you reside outside the United States you will be out of luck for a while. Nevertheless there is a very easy way to sign-up and use the service from anywhere in the world, if you are willing to jump a couple of hoops. Note you still won’t be able to buy any music through the service, but you will have access to the free storage and streaming service for you own songs.
