Google Music adds key backup feature

Google Music hasn't been making a lot of noise lately and is, in some ways, in danger of being overshadowed by other cloud music sites. But the Internet giant has roared back with the addition of a key backup feature for users.

Starting immediately, Google Music users are able to instantly restore their music collection with a single click. That applies to both purchased music and any songs they've added from their own library.

It is, of course, a direct response to Apple's iCloud, which automatically backs up App Store purchases, but also lets users backup music from other sources on their hard drive – for a price.

Google Music's new features don't appear to carry any charge – and they're being targeted at the Android audience, though PC users will able to use them as well. The only catch? Users are restricted to two downloads each via the Web interface.
